post 06 April 2023. Desktop iMac 2020 Ventura 13.2.1
I am getting black rectangles in project windows in Affinity Designer V1. They are randomly sized and scattered across the screen.
It seems to happen if I have several tabs open when I've left the computer in sleep while I go away for ten minutes and come back and switch between tabs.
Wondering if this is a software issue or a memory / storage issue.
Is my SSD about to fail, is my RAM faulty, is Designer demanding too much from my system or something else? any ideas / solutions would be great...
Cheers,
Sam.
