Not sure if I’m posting this in the right category, but I stumbled upon an issue today and after finding a fix I thought that I’d share my fix and hopefully some changes can be made to prevent such problems in the future.
I was encountering weird visual glitches - ghosting like effects around the edges of the screen when opening Activities Overview in Gnome 40. Screen recording software didn’t catch this (the affected areas appeared black), but I did record a video with my smartphone:
fortunately I’ve found this bug:
someone commented there that the issue there might be some kind of GDM theme. In fact in my case uninstalling manjaro-gdm-branding resolved this issue.
My suggestion would be to update manjaro-gdm-branding or force remove it in some neartime update in order to prevent more people from having this issue
