Due to lack of activity I did some more searching around, I didn't find anything new and exciting. I did find a description of a slightly similar problem, but the solution didn't apply to me (I'm not using the relevant zoom plugins. See http://ubuntuforums.org/showpost.php?p=3664399&postcount=13 for more.)
I should add that I have general mouse pointer problems which may be related. I tried setting HWCursor off in the display device section of the xorg.conf but that produced even less desirable effects - the mouse pointer is not correctly composited when drug over composited windows. Since I'm using xserver-xgl, that's pretty much everything but the desktop. Moving the non-hardware cursor over avant-window-navigator, for example, resulted in all kinds of trashing all over my dock. As a big collection of composited windows this is not much of a surprise. However, my mouse pointer also disappears when I hover over practically anything, especially resize handles. When mousing over the window gadgets it looks like there's something on top of it that causes it to not be drawn, perhaps something tooltip-related? It seems like something similar happens to the resize pointers. Sometimes they are visible, sometimes not (usually not.) -- Image corruption around the mouse pointer https://bugs.launchpad.net/bugs/228861 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
