18562	guest screen flickering by 3d acceleration on	siriusjt		"Hello,
My Windows 10 guest screen of apps in Ubuntu-18.04 host shows flickering and/or overlapping.
- Flickering 3~5 times while the tile menu brings up by clicking Start button
- Overlapping top-left area of a window especially graphical apps, e.g. youtube, web browser
I did many googling and reading virtual box forums with similar issues and solutions but no effect for me.
- Turning 3d acceleration off is a solution but drawing is too slow!
- export CR_RENDER_FORCE_PRESENT_MAIN_THREAD=0 in /etc/profile.d/my-cr-test.sh - no effect
- replace /usr/lib/virtualbox/VBoxOGLrenderspu.so with compiled one from source codes - no effect
My hardware and software:
  - AMD Ryzen 5 2600 16GB: Ubuntu 18.04.2 LTS
  - NVIDIA GeForce GTX 1050 2GB: nvidia-driver-418  
Please check it.
