Text will not display in opengl applications when graphics acceleration is turned on for windows Xp. My app uses Qt 4.6.2 so i tried their opengl examples and their simple paint2d sample which draws some text also fails. in my programs case the text is rendered as garbage pixels on the screen, in the Qt example it just refuses to draw any text. if i turn down graphics acceleration to the level that turns off direct draw then the sample works though we don't use direct x so i am assuming the level where it fails is more than turning off direct x. I have had this problem with version 5 and 6.
