Since the introduction of programmable pipeline my CEGUI based windows are messed up. The only thing visible are the window frames and backgrounds. No buttons, text, etc. It looks a bit like CEGUI got only one pass at its rendering (but so far I'm just wild guessing).
For CEGUI rendering a dummy Scroll object is used placed above everything else:
I'm running Linux with Intel GPU (GM965).
(BTW I experienced the same error as Jim in the other thread and be6b57a fixed it for me as well)
Any ideas what I should check / modify?
Anyhow I'll try to build a debug version of CEGUI and try to see what happens there ...
