New iMac M3 and flickering background

[nagoodman]

I hope someone can help me. I finally got a new computer iMac M3 and everything is great except my background keeps flickering from gray to black when working only in Affinity Photo 2.2.1. I've looked in settings and tried using Integrated  GPU only but that didn't do it. Any help would be greatly appreciated, thank you.

Try out OpenGL instead of Metal under the APh preferences performance settings.

Thank you so much! That did it. I tried to find OpenGL before but could not. It automatically checked metal for use with M3 iMac. Again thank you.

Hi @nagoodman,

I suspect this is the same bug that affects M2 Macs, that we have logged with the Developers.  Can you just confirm if your Mac is set to use the display profile called 'Apple Wider Colour Sharing Profile' or if the images you are working with use that profile?

[nagoodman]

My display just says iMac for profile and the images I am working on is Adobe 98. I do not see the profile you listed above anywhere in ColorSync either in my library or the system library. Thank you for following up on this.
