STEPS TO REPRODUCE
1. on MacOS Apply any G'Mic filter

OBSERVED RESULT
When the cursor enters the canvas it gets totally or partially erased.
This is preserved only for that step, in the video after undo/redo the canvas is shown, but if the pointer enter the canvas the textures are made transparent (as shown in the attached video). Adding new strokes does not inherit the issue, but the stroke steps from gmic will always preserve this issue.


This seems to be related to the new threaded texture buffer patch. It is not present on windows according to my tests.

I can no longer reproduce this.
