[Qemu-devel] [Bug 1749223] [NEW] mouse offset or invisible wall 2.11.0-3

[zlice]

Public bug reported:

(There was another post, I'm not sure if it is related though. Also not
sure if it's Arch related, I wouldn't be surprised as I normally use
Gentoo and have less problems with Gentoo.)


qemu-system-x86_64 -enable-kvm -M q35 -cpu host -m 8192 -vga vmware -smp 
4,sockets=1,cores=4,threads=1 -drive file=/path/to/my.img,if=virtio -soundhw 
ac97 -usb -monitor unix:/tmp/qemu-mon,server,nowait -usb --usbdevice 
host:0000:ffff -device vfio-pci,host=00:00.0 -alt-grab &


When I grab the mouse in/out of the VM I tend to get an "invisible wall" half 
of the time.
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.
