I don't think the trace below is related to the cursor disappearing.

I found a pair of bugs (one in the intel driver, one in the X server)
which can cause cursor disappearances. I just sent an intel driver patch
to the intel-gfx list with the subject:

        [PATCH] load_cursor_argb is supposed to return a Bool, not void

I've posted the X server patch once, and will respond to some review
comments. Either is sufficient to get a cursor back, the intel driver
one means you get a working hardware cursor again, rather than using a
software cursor by mistake.
