virt-manager / spice mouse passthrough breaks in v6.7.3

[sh3ll4rpw]

I run Arch in my VM.
After updating kernel from 6.7.2-hardened1-2-hardened to linux-hardened-6.7.3.hardened1-2 my spice mouse is not working properly. My host mouse pointer is gone. It uses the lagging VM mouse pointer.

I downgraded back to 6.7.2-hardened1-2-hardened and now everything is ok

Try adding gather_data_sampling=off to boot parameters.
