I’ve talked with Chris on this one and I’ve reported this with UE-31051. This is something that has been passed along to Samsung and Qualcomm to investigate for the moment.
Do you see a message like this one in LogCat?:
W/Adreno-GSL(32053): : ioctl fd 34 code 0xc040094a (IOCTL_KGSL_GPU_COMMAND) failed: errno 35 Resource deadlock would occur
