If you are using Maya 2011 on Linux and a Wacom tablet, you may encounter refresh problems in Maya.
To workaround this problem, download the updated library (libQtGui.so.4.5.3) and replace the library that is currently on your system. Root permission on the system is required. This library works with any Maya 2011 release.
Note: For back-up purposes, you should save a copy of the library that exists on your system to another location before replacing it. The default location of the library is: /usr/autodesk/maya2011-x64/lib.
See QTBUG-3839 for more information: http://bugreports.qt.nokia.com/browse/QTBUG-3839.
