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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
