Glitch caused by w10 UAC prompts

Post by runloganrun »

Hey everyone. I've attached a screenshot of what happens. Basically, every time w10 needs an admin ok, it changes the resolution of the virtual machine, which is running in seamless mode.

ctrl-lx2 sets it back to normal, but that's annoying when I have a lot of going on. Can anyone explain why this is happening, and suggest a fix (preferably one that doesn't involve disabling the prompt)

I'm on Debian (buster), using Virtual Box "6.1.22 r144080 (Qt5.11.3)"

I have not dealt with UAC prompt problems myself. But I do remember that there is a setting for UAC that does not dim the screen when the prompt is displayed, which might help.

Also try disabling Settings > Personalization > Colors > Transparency Effects in your Windows 10 VM.
