Upgrading from 6.1.38 to 6.1.40 brings strange window behavior in Windows 10 guest
Posted: 29. Nov 2022, 19:59
My host system is Fedora 35 KDE spin running a 6.0.9-100 kernel with dual monitors, one 4k and the other 1920x1200.
Running a Windows 10 guest on VirtualBox 6.1.38 runs normally.
Running that same Windows 10 guest on VirtualBox 6.1.40 results in flickering windows (I see this on the 4k display but have not tried it on the smaller one), seeming to warp left and right by several hundred pixels. The mouse pointer appears mainly at the right-hand warp but will appear sporadically at the left-hand warp. If you can manage to catch the edge of a window with the left-hand incarnation of the pointer, you can drag it left or right, but if you release it at where you think the right-hand warp is because you think that is the predominant image, it will immediately warp to the corresponding left-hand warp position.
I'm not saying the warp positions are fixed. Just that for any position of the pointer on the screen, there is a right-hand and left-hand position and the right-hand position is what you see most of the time, but treating a windows as if that is its actual position doesn't jibe with the pointer.
A few weeks ago, I upgraded to the first or second general release of VirtualBox 7 and it also had similar display issues, so reverted to 6.1 almost immediately.
Has anybody else seen this kind of behavior? Or is there a way to fix the issue?
Thanks.
