Re: [Chromium-users] readback spu with sortlast for large window size

[Qin W. <qi...@wa...>]

Hi Brian,

In the Chromium doc, I notice the use_osmesa and pbuffer_size can be 
configured for the off-screen rendering. I just wonder if Chromium can get 
hardware-accelerated support when rendering this way ?

Many thanks,

Qin
