0.3.6 includes gtkglext. In the next 0.3.7 release we will replace it
with Cairo. gtkglext fails horribly when combined with Compiz making
it pretty much unusable for that scenariop. If you want to enable gtkglext
in the current Mandriva build  that's fine, you'll simply get better
scaling support when you upgrade to next release
