I purchased Parallels Desktop 13 when it was the current version. When I initially got my Windows 10 VM up and running, I had no issues whatsoever. However, I've recently began to notice a few things not working properly. The VM as a whole has become a bit slow and laggy, and coherence mode no longer works (gray boxes appear instead of the Windows applications). I can only imagine that these issues with my outdated Parallels are a result of me recently upgrading to Catalina. Has anyone else had these issues? Will it all be solved by upgrading to Parallels 15? Thanks!
