1841501 - Firefox stops reacting to hover over events properly

Status: UNCONFIRMED

(Core :: Widget: Gtk, defect)

Description

Attachment: Screenshot from 2023-07-03 12-22-38.png

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/114.0

Steps to reproduce:

Periodically (maybe daily, maybe a few times a week, I think?), Firefox seems to stop reacting to my hovering a cursor over things as it normally would. It is unclear to me what is causing this.

Actual results:

I normally notice this first in Gmail, where hovering over a message in my inbox no longer shows the Archive, Delete, Mark Unread and Snooze buttons. If I go to other sites like https://nabeelgit.github.io/cursor-changer/ then the cursor does not react to hovering over the boxes.

Expected results:

If I quit all windows and reopen them then it acts like I expect again, with the Archive, Delete, Mark Unread and Snooze showing and the cursor changing on https://nabeelgit.github.io/cursor-changer/

Please let me know if any further detail would be helpful. I am running on Ubuntu 22.04 using the normal snap:

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Does quiting all windows mean that Firefox is getting restarted? The next time it happens can you get a profile using https://profiler.firefox.com/ and then upload it and share the link here.

Is this what you need?

Actually, even creating a new window after it happens seems to resolve it, rather than requiring a whole restart of Firefox. It appears that the issue may even be window dependent; I believe I had multiple windows open and the main one had this occur when other windows I had open seem to be behaving normally.

Please try plain mozilla binaries:

And also attach about:support page.
Thanks.
