Bug Description
On a setup with two screens (primary: laptop screen, secondary: external monitor via thunderbolt & docking station), when moving the mouse from the primary to the secondary screen, the mouse pointer becomes invisible. Waving the mouse and clicking on windows sometimes helps.
Journalctl shows "Failed to post KMS update: drmModeAtomicCo
The issue started occurring 1-2 weeks ago, I suspect immediately after installing system updates.

If there's a kernel stack trace mentioning "drm_atomic_ nonblocking_ commit" around the same time then please also paste that here. It's not yet clear if this is mutter or the kernel's fault.
Likely workaround: Add to /etc/environment
MUTTER_ DEBUG_FORCE_ KMS_MODE= simple
and then reboot.
