+++ This bug was initially created as a clone of Bug #1615098 +++

Steps to reproduce:

-seems to happen on its own after some time
-couldn't find a specific way to reproduce but I dont have to wait for long
-if I detach a tab in its own specific window, then everything is working in this window while the problem remains in the previous window
-may need a second monitor ?

Actual results:

-Hovering on items with the mouse seems to have no effect, the cursor won't change icon depending on the page element that is hovering (e.g. link, or text field), and elements won't highlight (for example when hovering over tabs).
-mouse doesn't highlight the selection until mouse release
-same with scroll bar
-If I restart the browser everything goes back to normal
-if I open a new window, the issue will go away

Expected results:

Nothing of the above mentioned should happen.

When mouse is working correctly, and going above the hyperlink wayland in blue on the picture, a popup "NEW - [meta] Firefox Wayland port" appears

and in this window, I can open a new tab, and play with google map (for example)

When mouse is not working correctly, and going above the hyperlink wayland in blue on the picture, nothing happens.

and in this window, if I open a new tab, I can't use google map (for example)

but If I detach the new tab in another new window, then everything is working in this particular window

Not sure if it's the same issue or not, but on Wayland, the cursor started being stuck sometimes. For example if you try to drag an image it changes to a hand from a pointer, and then just stays a hand until you restart Firefox. Sometimes it gets unstuck after a while.

I can open a separate bug for that if needed.

Several people have put some comments in the old https://bugzilla.mozilla.org/show_bug.cgi?id=1615098.

I hope people are going to comment here instead.

Please Mozilla Firefox dev, can you tell us what we could to to help you correct this bug :

do you need any specific logs, configuration files, etc...

Same here. Interestingly I have several fullscreen browser windows and only one of them is affected.

A possibly-related problem: the browser thinks that this window is the size of the main screen and it cannot be dissuaded from this notion. When I click the Maximize button on the top right, the browser window ends up somewhere on the screen but it cannot be resized, there are no window controls in the title bar any more, and I can no longer scroll to the bottom of the content. In other words, it behaves as if it were still a fullscreen window: I suspect the reason for this behavior is that in addition to not getting mouse-moved events, the browser also ignores resizing (and related) events on this window.

Would it be possible to try to find a regression range using mozregression, if this is reproducible on your end?

$ pip3 install --user mozregression
$ MOZ_ENABLE_WAYLAND=0 mozregression --good 100 # Or last good version

on my laptop, not easy enough to reproduce (5? 10 minutes? of usage of firefox before it happens) to use some kind of "git bisect" method

Current configuration after a recent apt upgrade (bug still present for me, same workaround as before, put the tab into another window) :

I have the same symptoms... but they didn't happen with 104. This only started with 105 for me.

Also, it takes some time before it starts happening for me.

Adding my name to the list of people experiencing this problem.

Running Pop!_OS 22.04 with Wayland and Firefox version 105.0.1.

also, when this starts, the window resizing isn't working either.
it just cutts off everything not in the window

running gnome 42 on arch

I already described that (somewhat more elaborately) in #11.

Not sure if it's the same issue or not, but on Wayland, the cursor started being stuck sometimes. For example if you try to drag an image it changes to a hand from a pointer, and then just stays a hand until you restart Firefox. Sometimes it gets unstuck after a while.

If we assume that, on some windows, Firefox (or one of the libraries it uses) loses or disables part of that windows' event handler for some weird reason, then that does seem to be the same bug.

Same problem, I've been having this issue for a while now. I use a second monitor and it happens randomly after I "Open a New Window" in Firefox. I use Alt + Tab a lot and "Inspect" page and use the "Responsive Design Mode". I also drag tabs between the Firefox windows often. I can't seem to pinpoint exactly when it happens. Restarting the browser is the only way I have found to fix it.

Also my browser tabs get stuck in place sometimes, and I can no longer drag them to rearrange them. Not sure if this is related or a separate bug.

Firefox 105.0.3 (64-bit)
GNOME 42.4

Same issue happening here:

  • Dual monitors
  • Archlinux GNOME 42 using Wayland
  • AMD GPU

Seems to happen randomly, but most commonly when switching focus.

(In reply to Martin Stránský [:stransky] (ni? me) from comment #5)

This is not Wayland but XWayland - X11 emulation on top of Wayland compositor.

This happens on regular Wayland all the same, so it's not XWayland related.

Blocks: wayland
Summary: [XWayland] Mouse hovering broken on Firefox 104 → [Wayland] Mouse hovering broken on Firefox 104

Hello, I don't know if this helps, but I've been experiencing the same bug described both here and in https://bugzilla.mozilla.org/show_bug.cgi?id=1615098. I'm running Ubuntu 22.04.1, with xwayland as my window protocol.
\

I'm also experiencing this bug on just normal X11 as well, so it may be unrelated to the window protocol entirely.

I'm facing the same problem but with MOZ_ENABLE_WAYLAND=1. When I start Firefox with MOZ_ENABLE_WAYLAND=0 the mouse hover works as expected.

This stopped happening for me for some time now (Wayland mode, Firefox 108.0b7).

Same issue here on Gnome 43.2 with Firefox 107.0.1 on Archlinux with a multimonitor setup under Xwayland. This has been happening for several months now.

Same here with Gnome 43.2 and Firefox 108.0.2 under xwayland. Happening for a long time.

Still happening to me on Firefox Developer 109.0b9, Gnome 43.1, Wayland.

I have to open a "New Window" and drag all of my tabs into the new window to get the cursor hover back.

Also happening to me. It feels like a regression of https://bugzilla.mozilla.org/show_bug.cgi?id=1615098
The problem is mostly the same.

I just found the workaround of moving the tab to a new window. I have to move all tabs to a new window to be able to have the hover ability once again.

Same here, happens on wayland and xwayland, I have 2 monitors and an amdgpu.

I found another workaround that's slightly faster than moving windows to a new tab. Just toggle the Title Bar (left click white space next to the tabs / Customize Toolbar / toggle title bar on and off )

Doesn't work for me, which might be related to the fact that Firefox also doesn't see window resizes and related events when it's in that state.

NB, I don't see a title bar toggle in the tab that opens when I go to "customize toolbar", but on my system pressing the Alt key acts as a title bar toggle.

Might be a GNOME thing. For me Alt brings up the Menu Bar while toggling the Title bar checkbox toggles between gnome / adwaita window decorations and no window decorations.

I have the same issue, restarting firefox fixes the issue but it happens again frequently.

Ubuntu 22.04.2 LTS
GNOME 42.5 Wayland
Firefox 110.0.1 (64-bit)

GNOME, Wayland, Firefox 111.0–111.0.1, I experienced this issue (after a while, window decorations disappear, and hovering has no effect, unless mouse buttons are clicked or mouse wheel is scrolled) only when multiple monitors were connected. I usually have two Firefox windows, and It happened to one window (then I restarted Firefox to work around it).

It happened to me many times a day when running under Xwayland (but only when I had two external monitors connected; never with a single builtin display). Then I set MOZ_ENABLE_WAYLAND=1, and the issue hasn't happened to me for more than a week. It's interesting that someone (comment #26) has the opposite experience regarding MOZ_ENABLE_WAYLAND.

I also have MOZ_USE_XINPUT2=1 if it matters.

I am also affected by this problem in Firefox 113.0.1, running on Gnome and Wayland. What I noticed is that it tends to start happening once I open videos on YouTube. If the cursor is over the video player element, it eventually disappears. Note that the video is not in full screen mode. If I move around my mouse a bit then the cursor shows up again but I eventually hovering is broken which causes stuck tooltips, broken drag and drop, etc.

(In reply to szszoke.code from comment #37)

If the cursor is over the video player element, it eventually disappears.

Which gtk version and Linux distribution do you have? There has been bug 1802877.

It's a really old bug but the thread is closed without a fix.
I'm also facing this issue on Wayland when using multi monitor. I noticed it's easily reproducible when I'm using alt+tab to navigate between windows. It's happening randomly so to reproduce this problem just keep using Firefox for a few minutes and try pressing alt+tab (or even sometimes it's just alt).

The problem doesn't exist on other browsers so I assume there is a bug in Firefox.

I updated my system since my reply but I will write down the versions once it happens again and post here.

I am running Arch by the way so I would guess everything should be fairly recent anyways.

It happened again. I also noticed that hover is updated if I scroll via the scroll wheel while the cursor is above things.

What does "Window Protocol" on about:support contain? wayland or xwayland?

xwayland

I don't know why default value for snap package is set to xwayland but when I force Firefox to use wayland by setting MOZ_ENABLE_WAYLAND=1 the problem won't happen anymore. Any chance to see wayland enabled by default in Firefox snap package in next release?

Just to share a new finding: I noticed that this bug occurs only when I open up and use VSCode or some other Electron based apps when window protocol is set to xwayland.

(In reply to Darkspirit from comment #42)

(In reply to szszoke.code from comment #41)
What does "Window Protocol" on about:support contain? wayland or xwayland?

It says xwayland unless I launch Firefox with the MOZ_ENABLE_WAYLAND=1 environment variable, in which case it says wayland.

I will have to test for a longer time but it seems that it doesn't happen with MOZ_ENABLE_WAYLAND=1.

Is there any downside to just making that the default whenever a WAYLAND_DISPLAY envvar is found?

Frankly, I've had it with X. See also #1855443.

TL;DR: xwayland bad, wayland good.

I had the bug since ... I don't know, weeks at least.

In about:support it showed it was using xwayland.

Found this issue 3 days ago, and tried Firefox with MOZ_ENABLE_WAYLAND=1. and the mouse issue did not happened.

I'll obviously comment if it happen again: 3 days is more than 0 but maybe not enough to be sure.

After days of testing with and without MOZ_ENABLE_WAYLAND, I think I can conclude that the bug only happen when using xwayland.

If anyone want to test multiple days with MOZ_ENABLE_WAYLAND, it works to export the environment variable in ~/.profile, like this:

export MOZ_ENABLE_WAYLAND=1

That's what I'm doing on Debian Trixie with Gnome, but it should work consistently, I guess?

Yes you'll have to log out and log in again from your Gnome session for it to pick the variable.

No longer blocks: wayland
Depends on: wayland-stable
Summary: [Wayland] Mouse hovering broken on Firefox 104 → [XWayland] Mouse hovering broken on Firefox 104

Firefox 121 stopped using xwayland, so it is fixed for me, even without MOZ_ENABLE_WAYLAND=1. Tried it multiple weeks without the issue triggering again. I'm now on Firefox 122 and it still is fixed.

From my point of view the issue can be closed.

Yeah we won't fix xwayland-specific bugs at this point.
