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.

Title:
Mouse pointer disappears on the second screen [Failed to post KMS
update: drmModeAtomicCommit: Device or resource busy]
Status in linux package in Ubuntu:
Incomplete
Status in mutter package in Ubuntu:
New
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: drmModeAtomicCommit:
Device or resource busy" from gnome-shell, which is perfectly timed
with when I move the mouse pointer to the secondary screen. There's a
kernel stack trace immediately before that message
(drm_atomic_nonblocking_commit).
The issue started occurring 1-2 weeks ago, I suspect immediately after
installing system updates.
