Hi everyone and nice to meet you!
I've been looking somewhere on this board to find someone encountering the same issue as men, and looks like I succeeded. So basically, the same thing is happening to me with Affinity Photo on my MacBook. The other softs (Designer and Publisher) are toggling smoothly with no delay at all.
I'm running the latest version of macOS Monterey (version 12.1) on a MacBook Pro 14" with the M1 Pro chip (10-Core CPU, 16-Core GPU and 16GB of RAM). I'm using the upper-scaled resolution option to "More space" but I tried to get back to the default scale system and the issue is still going. Here's a screen record so you can see it in action:

Thanks in advance for the help. ๐
