Deffered Technical Preview crashes on Mali GPUs

I tested the new graphics options that was added to this beta/preview, but i have a problem. It crashes instantly when i change it over to Deffered Technical Preview. I have tested it on Adreno and PowerVR GPUs, and it works fine. I even bought a high end phone with a Mali GPU (Common in MTK SoCs) to test it out. And i confirmed it that it only crashes Mali GPUs. Hope you fix this very quickly, since i have been waiting for this feature to be added.
