I'm aware it's way too late for thsi bug report, so I file it for the record in the hope you have an eye on it with the next release:
I use the firestarter lxde live iso for coping around partitions. This may take time ... and the scrensaver jumps in if you do nothing else, the screen goes black. After a new action, the desktop comes baack again, even the mouse, except you can't see it because the cursor doesn't appear.
Maybe it is worth to test this bug with the new lxde release which most likly will be a lxqt release and thus the codebase will have changed.
BTW:
someone knows how to re-initialize the mouse/cursor (yeah, reboot, great, any other idea?)?
