I have been struggling for days to get my graphics card to work properly, but I keep getting graphical errors in my multi-monitor setup. Some areas of my screens go randomly black and don't fix until I hover over them with the mouse. I couldn't find anything in the journalctl about this. I'm using EndeavourOS, and I have installed Linux firmware, Mesa, and everything else, but I can't find the error. I'm about to lose my mind. I dont know is this a hradware bug or software
Your issue may be caused by an unsupported OS (EndeavourOS). I would suggest installing a supported OS such as (64-BIT) :
RHEL x86
Ubuntu x86
SLED/SLES 15
Windows 11
Windows 10
as indicated in the driver download page: https://www.amd.com/en/support/graphics/amd-radeon-rx-7000-series/amd-radeon-rx-7900-series/amd-rade...
The same things happen on Windows 10 and Windows 11.
