New install of ArcaOS 5.1.1: mouse and video corruption on VirtualBox

<< < (2/2)

Neil Waldhauer:
In UEFI mode, I also have to run at 3840 x 2160 x 16. In Legacy mode 3840 x 2160 x 32 works OK. VESA BIOS in 4K mode is flakey on several of my computers. This is one area where a video driver would be a plus.

I tried 32-bit color at first, but the workplace shell kept freezing up. 24-bit worked better, but moving and resizing windows left bits of the windows behind on screen.

How do you setup 16 bit? I've only 16M colors and no other selection available here with Panorama (bare metal).

Neil Waldhauer:
If you are in UEFI, then, on some computers, you can also turn on CSM support, and that will provide a 16-bit. On other computers this is not available, and you are stuck with 32-bit color.
