Ok, that's the memo i hadn't gotten here 😅

Frankly, sounds like a typical dead on arrival card to me, especially if @fuchsiii is the only one having that problem.
RMA it. And if the problem persists we can assume a driver bug.

For all the critics one can have on Windows, and i have oh so many, the graphic drivers got pretty robust and can handle a counted/faultish graphics card.
Linux can't that much and falls on its face. At least in my experience.
