Probably; this sounds remarkably like some hardware (Neomagic?) that I
had forever ago that had some bugs in either the software or hardware...

Yes. Specifically, X will do a software cursor if it needs to, but likes
to use the hardware support.
Most modern hardware supports cursor drawing, but occasional glitches
prevent it working correctly or reliably.
Check the notes for the X server to see if you can turn off hardware
cursors and that may help.
