It sounds like I have the same problem. There is a virtual wall where the mouse cursor goes from the guest window to the host desktop. This virtual wall/cut off point is consistent. Moving the mouse faster seems to break through this wall and puts the wall at a different place.
For me this happens on a host with ubuntu 19.10 with wayland. I don't have the issue on ubuntu 19.10 with X. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1749223 Title: mouse offset or invisible wall 2.11.0-3 Status in QEMU: New Bug description: (There was another post, I'm not sure if it is related though.

I can push past if I fling the mouse through it but not if I slowly keep moving down. The direction always seems to be down when I hit a wall (so a Y offset? maybe?) This has been happening since at least version 2.10. Not sure if "-alt-grab" has anything to do with it, that'd be my first guess.
