Chromium DEV - new update disable all GPU optons on FGLRX driver

Hi,

From last time I use Chromium DEV PPA for Ubuntu and all GPU options work fine.
Now after two or one latest update all GPU options in chrome:gpu is disabled - I have only software mode, not like before hardware accelerated. Only software...

I try enable it but I can.

I try log my browser in terminal:

Also in chrome:gpu I have in log message:

"Log Messages
GpuProcessHostUIShim: The GPU process exited with code 256."

Also look at my graphics feature in chrome:gpu:
