I have been having this issue for a couple of years but always put it down to the particular brush set I was using or something unique to my setup, however, I have now experienced it on different macs and with multiple brush sets which makes me think it must be a wider issue.
Affinity Photo 2.1.1 crashes after varying lengths of time when using certain brushes in a specific way. I have encountered it when using 'wash' style brushes as a mark-maker, rotating and placing them multiple times in a short period of time.
• The issue happens with Hardware acceleration on and off.
• It happens on Intel and Arm-based Macs
• It has occurred on at least the last 2 versions of macOS including Ventura
• It also happens whilst in Affinity Publisher Photo persona
• Affinity Photo 1.x up until the latest version of Affinity Photo 2 is affected
• It happens across all files including newly created ones
• Brushes affected include Master Watercolor Light Wash 3 and Dreamphography Smoke 3 Stamp
I have attached the crash report, a copy of a test file, and a video showing the issue occurring (the crash occurs when the screen goes black).
Please let me know if there is any more information that might be of help. Thank you!
