Extra frozen / stuck mouse cursor after screen lock / sleep without fractional scaling

[Mr.Gosh]

After a screenlock the appears a second, fixed or frozen, non-moveable mousecursor that vanishes after reboot.

I have no fractional scaling active (as this seems to force the problem for others)

I switched to wayland - I think this happens since than.

Sounds like you need a slightly newer kernel.
