Question Cursor bug

[macaron22]

i recently upgraded from a 1070 to an 7800XT and i noticed this weird mouse corruption when transitioning into another shape, for a split second it turns into a red horizontal line, i thought i might have been traces from DDU, but then i upgrade from win 10 to 11 doing a clean installation and the glitch still there, enabling cursor shadows seems to make it happen more frequently but enabling pointer trail seems to get rid of the problem

so far i havent had that many problems with the card just 2 occations of the driver timeout message when starting the pc, and one crash when playing a game, that it actually turned one monitor black and the other green (no text), and the pc restarted by itself immediatly after that

what im trying to wonder if this is a hardware issue and if i should return the card before it escalates into something worse

i tried posting on somebody else's old thread with the same problem but got told to start a new thread:

Right now its a problem that neither has addressed as it doesn't happen often enough for someone to be able to identify its actual cause.

USB and GPU both controlled by same controller on motherboard, so it might be interference in the signal sent to screen.

its not hardware as it doesn't happen in safe mode (this isn't a 100% knock out as safe mode doesn't put as much stress on the hardware) or appear in screen shots, so GPU isn't rendering it. Its in a layer inbetween. Its a software bug but whose... AMD or Microsoft?

SO far this is what we have

IT HAPPENS:
-using 2 displays
-happens on both displays when both displays are active

IT DOESNT HAPPEN:
-on safe mode
-using 1 display only (tried both displays) even when running a game in the background
-activating pointer trails

THINGS DISCARDED AS THE CAUSE
-screen resolution
-screen frequency

The problem with not knowing what causes it is it makes it really hard to replicate it.
It needs to happen to someone who has the technical knowledge to be able to drill into problem and figure it out. I don't even pretend to know how they would do it. Must be a way to analyse the signal sent from GPU. I expect there are tools that can do it. I am not suggesting you do it, just speculating.

Problem is it doesn't happen to everyone. So recreating it in the perfect circumstances would be hard.
