Mouse cursor blinks while coming out of suspend

[Damian Yerrick]

When I wake my ThinkPad T450 running Xubuntu 23.04 from suspend, sometimes the mouse cursor flashes 1 to 3 times before the form to unlock my session with my password appears. These flashes did not happen in Xubuntu 22.10.

Suspicious lines in the output of `sudo dmesg` around one wakeup:
