Blank White Background Pinpoints Cursor and Flashing Bug on EndeavourOS

Hi everyone,

Blank white screen Background has been very helpful for spotting display problems like screen flashing and glitches. After updating EndeavourOS today, I used a white background to pinpoint the flashing problem, which occurs after the system boots up and leaves a white cursor stuck in the top left corner.

When I try switching to another TTY, I briefly see the login prompt, but the screen flashes again, leaving only the cursor visible.

I’m using Optimus Manager and found a suggestion on the forums to recompile it, but I have not done this yet and cannot do it at the moment.

Is there a way to resolve this issue without reinstalling the OS? Any suggestions?

Might you have recently enabled HDR in your display settings?
