Comment 32 for bug 2017101

Host OS: Ubuntu 22.04, HWE kernel. I believe Simon Quigley already took care of the GA kernel testing.

Windows 10 Pro and Ubuntu 22.04 were used as the guest OSes.

Win10 notes: Hit a strange issue with 3d acceleration after installing Guest Additions - the taskbar and start menu went transparent. This is a known issue that is about four years old according to Reddit (https://www.reddit.com/r/virtualbox/comments/f96q4s/windows_10_build_2004_and_guest_additions/) so not a regression AFAICT. Disabling transparency seemed to fix the issue. Everything else worked well.

Ubuntu 22.04 notes: With Guest Additions and without 3d accel, I get strange graphical corruption. Also there are some cursor animation anomalies (namely animated cursors seem to not actually be animated at all). Both could be reproduced with the older version of VBox, so not a regression.

Also with Ubuntu 22.04, there was also a bit of graphical corruption in 3d accel mode, but less severe and it was transient (went away after a guest reboot). This was with the -proposed version, I couldn't reproduce it more than once with -proposed and didn't reproduce it with the earlier version.

This gets a stamp of approval from me, @tsimonq2 if you also completed your testing without issues, could you mark Jammy as verification-done? Thanks!
