I know it's issue of wallpaper service... it is modified version of Robert Green's wallpaper service, forced to create ES 2.0 context. Previously I have added limit for devices supporting only ES 2.0 however it didn't help. That's why i removed it and modified code - when it fail to create 2.0 context then it will try to crete 1.x and disable shaders, but looks like it didn't help much for devices with ES 2.0, but should help devices with ES 1.x only.
