(Get the code!)
I can reproduce the problem on two computers, both running fully-updated 24.04 beta.
For me, the bug appears if all of these circumstances are met:
- /org/gnome/
- one of the windows is focused
- the Desktop Icons NG (DING) extension is enabled in extension-manager
The first two matches earlier observations here, the third one looks like new information.
As you toggle the DING extension, this vertical 1px wide bar quickly rushes to/from the right edge of the screen. It suggests that it's not that the background isn't drawn properly, it's rather that DING explicitly draws this line on top of it (and shows a brief animation when getting enabled/disabled).
This also aligns with the observation that a window needs to be focused -- probably if focus is taken away from windows by clicking on the background then DING receives the focus, and apparently it's DING's unfocused state combined with Ambi/Radi themes that results in this glitch.
I'm almost certain that this is a bug either in DING or in the Ambi/Radi themes.
It's probably not related to the graphics card. One of these computers has an NVidia (nouveau driver), the other one has ATI Radeon. Scaling is probably unrelated, too. The glitch is seen on both Xorg and Wayland.
