No issues here (14" M1 MBP + Studio Display). A lot of the weird issues with multi-displays went away on the Intel to ARM transition. The author is using an old Intel iMac Pro. There are of course window logistics problems but they seem to be manageable and Apple do the least surprising thing I find. I would suggest the author tries using a windows laptop with 1920x1200 at 125% scaling and an external 4k display at 150% scaling and the associated weirdness. They will come crawling back to the mac in tears of joy very quickly. Literally at the moment all my icons have gone back to 100% scaling and are tiny. The entire rest of the display is scaled fine, apart from one app which is 100% as well. This is every fucking day on windows. Edit: also spending 20 minutes replugging the damn monitor because it doesn't detect it the first time either (Dell P2723QE)
