1723708 - [wayland] [sway] Firefox UI stops drawing until window loses focus

Status: RESOLVED DUPLICATE of bug 1717957

(Core :: Widget: Gtk, defect)

Description

[luis.pabon]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Use firefox normally.

Actual results:

Occassionally, firefox UI will freeze - it continues to work, but does not re-draw. If a page is shown, the page itself works fine (scrolling, interacting with elements) but invoking FF UI elements does not result on the window re-drawing.

Once the window loses focus, some UI elements update (eg if a new tab had been opened, the new tab draws, but not the actual tabs themselves).

I seem to be able to trigger it consistently by invoking a submenu in a context menu - eg right click on a tab -> close multiple tabs.

It looks like the newer context menues do not trigger this behaviour - I can click on the hamburger menu and go to a submenu (like help) and this does not cause the UI to get stuck.

Re-scaling the display fixes the window for a while.

If I open a new window, the new window seems to work normally while the old window is still stuck.

Attaching video recording.

Expected results:

None of the above.

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

Please try latest nightly. This is caused by paused compositor - Bug 1717451.
