Recently my HP workstation died so I have a brand new computer running Windows 11.
When editing files, any editing like increasing contrast, changing colours etc. will introduce random rectangular areas in the image of a random colour.
I have tried a number of things including compatibility modes and turning off fullscreen optimization etcetera. Nothing seems to help.
Is there a patch or a fix for this weird behaviour? I am using the most recent version of Affinity Photo.
All other software works correctly on the new system.
