Guest: Ubuntu 22.04
When booting the Guest OS, occasionally mouse support works only partially:
- Mouse clicks work in the left-side of the dock, but not with rest of the desktop
- Mouse cursor is correctly set and shows everywhere
- After right-clicking a dock item the context menu can be properly clicked
- In full-screen mode additionally the small top-right triple icon menu works as well (but not in windowed mode)
- Keyboard support seems to work properly, and if I e.g. open Terminal from the dock, keyboard input for the terminal works although mouse input doesn't work.
- Switching between PS/2 or Tablet as VM Pointing Device setting doesn't seem to affect the issue.
During guest startup there is also error: "[FAILED] Failed to start vboxadd-service.service".
Attached: two specimens of logs where mouse support works and when it does not.
