[Beignet] Beignet vs LuxRays, again

[Zou, Nanhai]

Hi,
	I have downloaded LuxRays and reproduced your issue.
We will look into that.

Thanks
Zou Nanhai

Hi，
	We will check.
	Did you modified the LuxRays to run it in Beignet?

Thanks

Hi,

I've just rendered the first picture using LuxRays and Beignet.
Observations:

 - During rendering, colored dots appeared all over the display at random locations
 - In the final result, there are black pixels
 - Fonts in some applications appear garbled
 - Rendering was slow (AMD's CPU-based OpenCL implementation was significantly faster on the same machine, an i7-3612QM)

I think there may be something wrong with the buffer management here, if the on-screen buffer and off-screen textures owned by different apps can be overwritten by OpenCL code.
