I fixed the pixel format missmatch, made width=height=128 and changed glDrawArrays like you proposed but still no change.

I just want to draw a 2D image which fills the entire screen. I don't want any 3D at all. Only 1 texture which covers the entire screen. The worse part here is that with the power of two limitation it seams that I will have a lot of problems, because with this limitation I can't match correctly the screen format. Usually the screens are 2x3 in proporsions, but power of two allows only 1x2 from what I understand. > Why do you enable blending after drawing and at all? > Why do you set up your matrices after drawing?
