1880756 - [X11/KDE] Navigation tab freezes

Status: UNCONFIRMED

(Core :: Widget: Gtk, defect, P2)

Description

[jourdelune863]

Attachment: firefox_bug.mp4

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

Randomly, the navigation tabs freeze when I'm on Firefox, this happens without any particular step, just suddenly when I'm browsing the internet. This can happen quickly after opening Firefox, or long after or never.

Actual results:

I can click on a navigation tabs but it doesn't open or takes a long time to open, what I noticed is that if I move a window from another application on my desktop that is currently open, the tab will stop freezing (for example I have Firefox and Libre Office open, Firefox bug when changing tabs, if I move the Libre Office window or change its size, then in this case Firefox will open the tab that was buggy).

Expected results:

It should open the tab when I click on it without freezing or high latency.

In the video, only Firefox was recorded but when Firefox wanted to change the tab, it was when I moved another window.

[BugBot [:suhaib / :marco]]

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

Can you try latest nightly from Mozilla with clear profile?
