1809732 - Fullscreen error, visible desktop wallpaper on screen edges

Status: RESOLVED DUPLICATE of bug 1763981

(Core :: Graphics: WebRender, defect)

Description

[Milo Wagnitz]

Attachment: Screenshot of YouTube video in full screen mode with visible edges on the left and upper side

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:108.0) Gecko/20100101 Firefox/108.0

Steps to reproduce:

I open a video on a website (mostly YouTube, but I've expected this behavior on other websites too) and enter full screen mode. I use two screens (second on the left side of my desk) and Windows 11 22H2 (Build: 22621.1105).

Actual results:

There is often my desktop wallpaper visible on the edges of my screen and the video and this edges move the video a bit down and to the right. When I leave full screen and enter it again, it displays the video correctly.

Expected results:

There shouldn't be any edges, which are moving the video a bit out of the screen and show my desktop wallpaper when watching a video in full screen mode.
