@Lee D Seems like after i turn of the hardware acceleration, it resolve the issue... so far, after a few try using the same file, seems like working ok. Thanks.

My lag is when i try to draw using my graphic tablet. Same file, but in my old imac (mid 2011 version), no lag but when i transfer the file to my mac mini (2018 years edition) with new MAC OS. It start to lag just after a few stroke.

Hi, I just transfer a working file from my old imac (mid 2011 years) to a mac mini 2018 with mac OS Monterey. It get lag very fast when I am drawing using pixel brush. I did a comparison with my old imac 2011, and strangely, the same file, same version of affinity designer, but it work fine in my imac with old Mac OS. In Monterey , it get lag just after a few brush stroke, which make it painful to work with. Is it the OS issue? because a Mac mini 2018 should not be performing worst than my imac 2011. hope the issue resolve soon thanks
