Just throwing it out there. There is this White screen problem in the wind. Have a read at [Only registered and activated users can see links. ]
But I don't think its our problem because most already have OpenGL 2.0. Here is rf711 device specs. [Only registered and activated users can see links. ]
This is what rf711 and I noticed, SP v2.35 0xDA4B38: DrawSetup() function called always 4 times on good device but 2 to 3 times on bad device. So we seem to be missing a call somewhere.
fyi, On SP 2.33 its 0xDA6ADC: DrawSetup()
