For me it's anything like excalidraw or something like Google sheets. They work fine until I change tabs and come back then it's blank. But if I move the arrow keys or scroll wheel then every comes in and out of existence or stays on the screen even if I select another sheet until I close and reopen the site. But I never noticed this issue before moving to Linux so maybe it's an issue on my machine
Idk for sure, but if excalidraw uses canvas then there are a lot more possible machine/OS specific problems that come up. Web browser features that hand tasks off to the GPU have gotten a lot better over recent years but there are still oddities like max shaders for a specific browser/OS/GPU combo that'll lead to some funny behavior.
ok so if its being passed on to the GPU then that actually makes me think its that. I bought this GPU used from a buddy and was having issue's with my wife's machine playing GTA5, I thought the GPU just couldnt handle it but maybe it has an issue
