I have Parallels 20 running with a Windows 10 Pro VM, allocated 16 cores and 64GB RAM. My host mac is a 2019 Intel Mac Pro with 32 cores and 200 GB RAM. I have 3 monitors, 2 studio displays and 1 Azus display in portrait orientation. My main monitor is one of the studio displays. When I enter coherence mode and drag a window to the other studio display (browser for example), the application becomes unusable on that display, and the application window becomes distorted (see attached image). Sometimes they will work for a few seconds, or until I full screen them. All I can do is drag it back to my main display, where it works fine. I have tried multiple settings, even reducing the resolution on the mac, but nothing seems to fix it. Dragging to the Azus display seems to be fine. It feels like a memory issue, but I don't see anyway of increasing video memory. This is incredibly frustrating, has anyone else experienced this?
