I'm running Ubuntu 16.04 guest on a Windows 10 host with VirtualBox 5.2.4. I have an Nvidia GTX 1050 graphic card.
I've followed all the necessary steps to enable 3D acceleration as in here, and everything seems to have worked correctly, if it wasn't for a constant pixel flickering affecting transparencies. The flickering also affects the upper bar randomly. Here is a screenshot:
The system seems to run a bit faster, and it's SORT of usable, but the glitch is very annoying. The solution given for this other problem didn't help.
What else can I try?
