So i have desktop problems on parallels. The windows background starts to go black over ikons and when I move the mouse around it makes more go black or black and white stripes??? Screen shot attached. This only happens on my laptop display not my external monitor
I'm seeing this issue as well. Just imported the VM and installed Parallels tools a couple of hours ago.
Hi @matthewh4 would you please create a new Windows virtual machine and check whether the issue persists or not. If your new virtual machine is working fine then log into the existing virtual machine and generate the problem report using this KB article and reply us back with the report ID.
This may be due to problem in monitor cable. May be the cable is not installed properly or may the cable is having some issue with transmission. Check this link to get rid of any cable installation issue or to test your cable - http://www.flukenetworks.com/installation-and-test
its 100% not a cable fault. First thing i checked. or a monitor fault It only happens when in parallels not when im on OSX
Try to increase the graphics memory allocated under VM configuration > Hardware also try disabling 3D Acceleration and check.
@matthewh4 do you still have the problem? I have the issue too and I dont' find out the solution. Please let me help
