Hi
I am having problem with npm electron GUIs getting white/black.
I am running PD 16 on MacBook Pro 16", VM with ubuntu 20.04 with 5.8 kernel.
I have read about something similar in kernel 5.11 thread.
Does anybody have idea how to solve this without uninstalling parallels tools? Or is just to wait for parallells to fix it?
I am also getting following crash in my syslog every time I resize the VM window:

If I understand your problem, when the app opens you just see a white box where the GUI should be? I also had this issue, and the workaround was to to disable 3D acceleration. I have also reported to Parallels but can you please also raise a bug?
 
Hi -- I just had a response back from Parallels Support about my similar case. Try this (with hardware acceleration enabled):

1. Make sure that the virtual machine is shut down (Actions > Shut Down). If it is in a suspended state, please run it and then shut down (Actions > Shut Down).
2. Go to the virtual machine configuration (see: https://kb.parallels.com/117287 ) and click "Hardware > Boot Order > Advanced Settings > Boot flags".
3. Paste the following text in the "Boot flags" field:

video.gl3=2

4. Run the virtual machine and see if the issue persists.

This fixed the problem for me. Parallels Support advised that their developers are working on a permanent fix.
