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?
