Painting - Glitched Square holes appear in painting

[Estoc]

Hello, I use Affinity Photo for digital painting primarily.  I have noticed this happen several times; when I am painting and switching between the brush, eraser, and smudge tools (+ performing operations with those tools), a square hole will sometimes appear on the screen.  This square hole can be painted over, but it cannot be undo'd, and restarting the program does not get rid of the hole.  This is a highly problematic issue, as it can ruin your image and progress you've made.

Try to disable hardware acceleration in Preferences >> Performance to test if this cures the problem.

This is not an easy issue to test as it does not occur frequently, and I do not know how to necessarily make it happen.

Hardware acceleration is a new feature introduced with version 1.9 of Affinity Suite. Unfortunately, the developers could not test all hardware constellations. Therefore, it may be that one combination works and others unfortunately not at the moment.

Deactivating hardware acceleration does not have a serious impact on the workflow. So deactivating is the only way to work flowlessly.

Alright, I will see if I can keep hardware acceleration off for the time being, I do hope the developers + staff looks at this  + fixes it however.

We are making numerous fixes for stability with the new OpenCL feature. I'd recommend trying the beta or at least following Mark Ingram on the forum to see when he posts about OpenCL improvements etc.
