Inpaint reacting quirky under Linux

Nobody has claimed this yet.

I know it's a lot but it's rather annoying that inpaint breaks after a while. I don't know how this happens but after using it a few times with different images, clearing all inpaint would leave the last inpainted checkerbox patch on the image, even if I load a new image into it. But that patch then is not included in the inpaint when generating.

Then it would happen that I can draw new inpaint patch on the image but the checkerbox patch never appears where I paint or sometimes it does appear as long as I am inpainting and then disappear on releasing mouse button.

In all cases the marked area would be correctly be inpainted by the model when I hit generation so it's probably entirely an UI issue.

This only happens under Linux with firefox.

Reproduce the inpaint workflow described on Linux with Firefox: use several images, clear inpaint, load a new image, and draw and release new patches. Compare the checkerboard overlay with the area actually sent for generation; done means the visible overlay is cleared, appears in the painted location, and remains synchronized with generated inpainting.
