I am running Windows inside QEMU on a Linux host. QEMU is running X with libinput. When I use the touchpad to control the mouse inside the guest, the pointer moves very rapidly and stutters. This problem does not occur when using an external mouse.

I have tried setting SDL_VIDEO_X11_DGAMOUSE=0, but that did not have any effect. Passing -usbdevice tablet helps, but I want QEMU to capture mouse input.

Has anyone else found a solution to this?

I am having the same issue.

The way it was solved was simply by:

  • opening the Control Panel in the Windows 7 guest,
  • open the Mouse settings
  • select the Pointer Options tab
  • finally in the Select a pointer speed section
  • Wouldn't this also affect pointer speed when using an external mouse, though?
