Hello, I have Parallels 13 and windows 10 as guest os. After the update to Catalina I have a strange bug and want to ask if someone knows a workaround except from updating to Parallels 15. If I use Parallels on my extern monitors everything works perfect. If drag parallels to my retina display of my macbook its really laggy and slow. Thats really strange, can I simulate parallel somehow that the monitor is not a retina display or does someone know a workaround? Greetings
Parallels Desktop 13 is partially compatible with macOS X Mojave so it might not be fully compatible with Catalina. We suggest you upgrade to the latest version and check.
