1795066 - Ctrl+Tab popup doesn't show up on dual monitor set-up.

Status: VERIFIED FIXED

(Core :: Widget: Gtk, defect, P3)

Description

[Emilio Cobos Álvarez (:emilio)]

If I enable browser.ctrlTab.sortByRecentlyUsed:true, and open Firefox on Wayland on my right monitor, the Ctrl+Tab popup doesn't show up. This is a regression from bug 1783437, Martin can you look when you have the chance?

:stransky, since you are the author of the regressor, bug 1783437, could you take a look? Also, could you set the severity field?

Sure.

Actually it works today after a mutter update, so maybe it's a mutter bug that's been fixed upstream...

Oh, nvm, I'm on an X11 session r/n...

AFAIK The ctrlTab dialog is supposed to be placed in center of screen. It's created as popup parented to toplevel window but we don't know our toplevel position so the ctrlTab dialog position on Wayland is purely random. The toplevel always looks like placed at 0,0 global coordinates.

As for this bug it looks like we use wrong coordinates based on recent monitor. We place the ctrlTab dialog relatively to toplevel but we use global coordinates according to monitor.

I've got slightly different mozregression range:
https://hg.mozilla.org/integration/autoland/rev/5abef032e22b7ea23e707fc12baf697f2b7bb2a5

But both looks a bit weird to me. On 104.0 the ctrl+tab popup is placed by nsWindow::Resize() regardless of monitor while layout coordinates are correct:

But latest nightly uses the same coordinates on nsWindow::Resize() and layout anchor:

so looks like there's a fix on layout side which includes correct monitor where the popup is placed but that breaks Wayland.

Err, looks like layout&Resize are the same.

Comment 10

[Martin Stránský [:stransky] (ni? me) (PTO, back on Feb 17)]

Ahh, I found it. It works if the main FF window is not moved. When it's moved (before ctrl+tab) it's broken. Perhaps we propagate recent monitor info.

Attachment: Bug 1795066 [Wayland] Don't report monitor/screen shift to layout on Wayland r?emilio

We can't report monitor/screen shift to layout on Wayland. It causes wrong popup placement as all window/popup coordinates are used relatively to parent on Wayland.
Also we can't get/set position of toplevel windows on Wayland.

Is this ready to land? :)
