Bought this monitor used a few months ago.

I dual-boot W10 for gaming and W11 for general stuff, both with the latest AMD drivers after cleaning with DDU.

Monitor works flawless in W10 during gaming or light browsing, however in W11 I randomly get a vertical band of pink static/artifacts, about 2 inches wide starting from the middle of the screen.
More specifically in W11 it tends to happen when I'm using Edge (latest version) and I usually have a load of tabs loaded (100+, some sleeping).

I tried a new DisplayPort cable same issue.
I swapped the monitor with a Dell potato and no issue in either OS so it's definitely this monitor.
Since W10 is perfectly fine I'm assuming it's some OS/driver issue specific to this BenQ XL2546 and Windows 11 combination.

Anyone else experienced this?

Have you tried a hdmi cable rather than display port? I recently had an issue where one of my monitors were giving me pinkish artifacts randomly. Swapped out the cheaper hdmi cable and issue dissapeared completely.
