Hi all,

I'm playing with the Dojo ARGB sample (http://labs.trolltech.com/page/Graphics/Examples) today, but weird things happen again...

When i compiled and ran the demo with Qt4.4.3, a *black* background appeared, rather than the expected transparent one; while i switch to Qt4.5.0-beta1, a compile error occurs this time said "undefined reference .. xrenderqueryextension"...

Anybody can kindly offer some learning about these?
Thanks in advance!

Do you have composition turned on in your xorg config?
