Mouse pointer doesn't work properly in Windows guests when scaling is on

Reported by: fandrei Owned by:

Guest type: Windows Host type: other


This problem started happening when I've got a 4k monitor and set scaling >= 150% in the guest OSes (as VBs built-in scaling makes the picture very blurry).

When I have mouse integration enabled, certain types of mouse pointers look messed up (see the attached video for an example). When mouse integration is disabled, the mouse pointer freezes in place when moving over certain locations on the screen (it seems that these locations are same as in the first case). Guests I tried so far - Windows 7 and Windows 10, both have this bug. This problem doesn't happen for Ubuntu. Hosts - Windows 7 and 10, and Ubuntu 20. All have this bug.

Could you download and install "Latest 6.1.x test builds" from, your bug should be fixed there. Do not forget to update Guest Addition in your Windows guests. Thank you for reporting!
