Description Rebecca Breu 2023-11-29 20:27:22 UTC

This happens from 5.2.0 onwards up to current master, but was fine in 5.1.5

STEPS TO REPRODUCE
1. Go to the gamut masks docker
2. Select a Gamut mask, click edit
3. The canvas now turns into the Gamut Mask Editor, but it stays completely grey.

It should show the color wheel and the current mask instead. If you know where the mask is supposed to be, you can still for example drag the shape, then Krita will start to update the canvas properly.

Confirmed, and by accident I found it's only when Canvas Graphics Acceleration is enabled.

There's an error logged when doing this, too, but it's apparently unrelated.
