Serious bug of video distortions in Parallels Desktop 13 on macOS High Sierra

Ok, this is awfully disappointing. I know it's a known issue. I keep having video distortions when switching between desktops in full mode with Parallels Desktop 13 and I wish I had stayed in the previous version. This sucks as hell. It is said to be resolved in Parallels Desktop 13.1.1 but I see absolutely no improvements, and still having these distortions. Can anybody provide some updates about it? Are you still working on this issue?
Please, let us know. Thanks.

 

same problem here, latest update did not fix this problem.
