Details

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0

Steps to reproduce:

Whenever firefox opens a popup window, for example a tooltip, dropdown or extension, that window flickers a lot. It is most noticable when I open an extension popup, for example Bitwarden. Every time you move the mouse around the window disappears and appears again.
I tried setting MOZ_ENABLE_WAYLAND=0, but it didn't make a difference.
Info:

  • Firefox 87.0 (86.0-2 was fine)
  • Sway 1.5.1 (wayland)

Actual results:

Popup windows flicker

Expected results:

The window stays on top all the time

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.

I couldn't reproduce this i3, so I suspect this is a wayland problem. Apparently setting MOZ_ENABLE_WAYLAND=0 doesn't make firefox use xwayland anymore, so I used MOZ_ENABLE_WAYLAND=0 WAYLAND_DISPLAY= firefox. There I can confirm as well that it's a wayland problem, since running on xwayland the problem goes away.
On wayland I tried setting widget.wayland.opaque-region.enabled=false (true by default), but it didn't make much of a difference.
