Thank you Sebastian for your support. I appreciate it.

Basically the screen is flashing. Some particularly views give a brighter image as no tone mapping was disable. At this moment if I move just a bit the image come back darker as expected from my tone mapping. It's little bit weird... I'm wondering if it is actually the mipmapping or if it is conflicting with an other stuff.
