<pre>Just for completeness: the bug is present in 4.5 final.
I've definitely seen FIFO overruns while the first two WM levels show the
cursor being on (PLANE_WM_EN set). I've never seen PLANE_WM_EN set beyond the
second level (LP0 and LP1 if I understand the code correctly).
I tend to have a gnome-terminal running, and gnome-terminal loves toggling the
cursor state, but I certainly don't need to have gnome-terminal in the
foreground to see this issue.</pre>
