Daniel, I think it isn't duplicate of other bug, because this problem with Firefox or Chromium appears only with Wayland session. And it is not windows flickering to black when resizing.

Unmaximizing is resizing, but OK...

Can you provide a video of this bug?

[Artyom Pozharov (artyom-pozharov)]

Compare the screenshot in "Attachment" (Windows flicker to black and white (like zebra) with Wayland session) and bug in the video: https://photos.app.goo.gl/3rvLkqJj6hZwSscw9 (Windows flicker to black with X.Org session). There are different bugs.
