[Bug 814777] [NEW] Occassional mouse cursor corruption on primary display

 

Public bug reported:

I often get into the state where the cursor on my internal laptop
display (1920x1080 resolution) gets corrupted into a single-pixel wide
vertical dotted bar (see approximate center of attached screenshot), but
the mouse cursor on my external display (1920x1200 resolution) is fine.

alternate cursors (window resize handles/text cursor, etc) either
display the same vertical bar, stretch it out a few extra pixels, or
cause the cursor to disappear entirely.

gnome-screenshot captures that include the cursor _do_ appear correct,
but not sure how much of that is screenshot-capturing-cursor-emulation
type code.
