Sorry for the late reply, I had the assumption that I was notified of changes
in this bug (I added myself to the CC list right now). OK

Versions:

nouveau-f1099810bb3cfe451877667a0224eb3d664e442f

Question: The patch: Always allocate 2 hw cursors. Is it worth another try
since I just downloaded my source minutes or seconds *before* it was applied?
Want me to retry with it?

drm-97fdadee6a79f9406a55c235ee46104814321152

I used a small script that changed the resolution. Kept it going for a minute
changing resolution every 2 seconds. The cursor stayed 'alive'.

Logging out and rebooting the X-server caused the cursor to disappear.

Trying to kill the X server just after the cursor disappeared made the kernel
unhappy and my system somehow crashed. (want more data?)

I also noticed something else: Whenever I change the resolution with xrandr. If
you move the cursor during the change the screen seems to go 'white'. I noticed
this as well sometimes when the X-server crashed because of the blob after a
severe error. However, if I stop moving the cursor, the screen restores after a
while since another xrandr -s [1-5] command is issued effectively restoring the
display.

Please let me know if you need more information / want me to do more testing.
