User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

1. Start Firefox in Wayland-mode on sway with a mixed DPI setup.
2. Right click somewhere (in the case of the log attached it was a Github issue thread, just somewhere on the plain white).

To produce the attached log, I used MOZ_LOG="WidgetWayland:5 WidgetScreen:5 WidgetPopup:5" WAYLAND_DEBUG=1 firefox --gdk-debug=events 2>logfile.log to run firefox.

Actual results:

The right-click context menu doesn't appear or is invisible unless I move the cursor onto it (by guessing where it should be), then it suddenly pops up.

This is hard to reproduce as it doesn't occur every time, most of the time the context menu behaves like it should/as noted one field further down. The attached log captures such an instance, where it happened to occur quite quickly after starting firefox.

Expected results:

The right-click context menu should appear immediately when right-clicked.

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.

Can you try latest nightly please?

Thanks.

From what I can tell, it does look pretty stable in nightly, so this could be a "fixed". I also observe that certain other flickerings in the context menu's sub-menus are gone with nightly (although I didn't test for too long as I'm testing with my main profile for reproducability and want to revert back to stable for the moment). We could close this for now and reopen it in case the issue comes up again once the current nightly becomes stable?

Okay, Thanks!
