[PPSSPP Android] Non-buffered rendering causes black screen

[abssalom]

Hello, Im using an Allwinner A31S based table and when i change the mode to non-bufered rendering (which is significantly speedy) i get a black screen but the game is still running, because i can hear the audio and the controls are working. It makes almost every game unplayable because with the buffered rendering activated, i need to turn frameskip at 3, and even with that, some games' speed goes under 50%. My gpu is a PowerVR SGX544MP2 which complies with OpenGL ES2.0, OpenCL 1.x, DX 9_3.

I think the OpenGl ES2.0 is the problem because i have another device (Xperia M2) that has OpenGL ES3.0 and it works perfectly.

Any ideas?
