Hehe, i suppose you have tried all the simple tricks, including changing kernel?
I just tried it myself, running yank kernel with smartdroid rom and it worked. Nothing is better than going back to full stock just to test it out, if it still persists then it is a problem, one that you could choose to forget, if your device still play's 3d games perfectly
. Might be due to too little ram to test 3d, resulting in heavy lag and thus a crash. But its all a theory.
