Thanks for info. Can you test this compiled demo, please? Just put it in bin directory and run.

Seems I catched known bug for GeForce FX videocards, that was released when FBO wasn't a standard... In my compiled demo I have removed one line of code(attaching depth buffer to FBO). So, maybe I will disable FBO for GeForce FX and switch to PBuffer, or I will try to make some "magic" with MipMaps(like described here), or... just disable depth buffer because ZenGL for now is 2D only

WILL
Thanks a lot

Fullscreen mode seems extremely twitchy under Windows 7 (x64); I have an nVidia 310m. I suppose I could always look for driver updates again, but just thought I'd mention this anyway. Keep up the great work, this has been working mostly flawlessly for me on both Windows and Linux.

edit: hm, looks like you have a bug tracker. I'll try submitting something tomorrow (it's late).

I can remember only one bug - first time when you close ZenGL application(with OpenGL render), screen will blink. After this no blinks anymore. If you have another situation, so create a new topic about it here
