There have been some fixes in this area recently. If it still happens, the output of running an affected application in valgrind --leak-check=full (with debugging symbols available for at least all Mesa binaries) would be useful. -- Earthling Michel Dänzer | <a href="http://www.amd.com" rel="noreferrer" target="_blank">http://www.amd.com</a> Libre software enthusiast | Mesa and X developer </blockquote></div> </div>
