Display issues

Post by jax200 »

I am running Ubuntu on a Windows 11 host. I have created many machines w/o issue, but as of late I am experiencing display issues with newly created machines. Specifically the VB window flickers with many lines. Sometimes when it is not doing this the cursor has a small reproduction of the display moving around with the mouse. I found resizing the window smaller eliminates it. Rebooting will sometimes clear up the issue, but other times it persists. It would be nice to know why this is occuring.

The Graphics Controller setting is default at VMSVGA. I have increased the video memory more than normal. 3D acceleration is not enabled. There is plenty of host CPU and memory. Guest Additions is installed.

Any suggestions? What should I look for in the Log?
