Video artifacts with latest update

I'm now noticing horizontal & vertical lines left as artifacts when I move open windows around in my VM. I wasn't
seeing this prior to the most recent update.

Anyone else see this?

 

try to reinstall Parallels Tools - this may be incorrectly installed video driver

 

Thanks for the reply... tried that and it didn't fix the issue.

 

Try to disable 3D support and animation and check the issue: Configure -> Hardware --. Video --> Uncheck one by one
Parallels Desktop Preferences --> General --> uncheck Use animation

 

Thanks, I will try that later today. One interesting thing is that I don't see this issue when connected to an external display with my MacBook lid closed.

 

that's actually interesting.. Please share the result once available
