This appears to be a bug in the way compiz handles keeping the size of animated cursors constant with enhanced zoom. It shrinks your real cursor down to nothing and draws a new cursor... when you zoom back out, it fails to resize the original cursor, but stops drawing the new one (since it's not needed unless you're zoomed). Thus after zooming out your cursor disappears.
See for example *http://forum.compiz-fusion.org/showpost.php?p=31025&postcount=2 *http://lists.freedesktop.org/archives/compiz/2008-May/003106.html *http://ubuntuforums.org/showthread.php?s=2b2236b207d0b819e05dcd0f6a3d1583&t=469891&page=2 *https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/163250/comments/5 ** Package changed: nvidia-graphics-drivers-180 (Ubuntu) => compiz (Ubuntu) -- firefox: mouse pointer disappears while page is loading https://bugs.launchpad.net/bugs/163047 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-180 in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
