noisy screen (flickering) when wiping between desktops

When wiping between MacOS desktop and a VM (three finger gesture) I often see flashing, flickering stripes or other noisy screen until the desktop settles.

(Macbook Pro, Paralles 13 Pro evaluation version)

 

Hello @ChristophK2 , please install the latest update of Parallels Desktop 13.1.0 http://kb.parallels.com/111603 and check if it works.
Thanks

 

I'm running the latest version.

 

Hello @ChristophK2 , please open virtual machine configuration http://kb.parallels.com/117287, go to Hardware Tab > Graphics > Increase the graphics memory to 512MB and Advanced settings > 3D Acceleration = Direct X 9 or Disable,
then restart Windows and follow the steps provided at http://kb.parallels.com/112476 and check if it works. Thanks,

 

It was set to 512MB and DirectX10

 

We expect the issue to be fixed in the next macOS High Sierra update.
