NVIDIA 334.16 Beta Supports 64-bit EGL / OpenGL ES

subsurfaces + alpha channel should cover that, no ?

For image uploading? They'd probably use texture from pixmap but, yeah, subsurface is exactly what'll be used for things like video. You'd still need an accelerated 2d rendering to replace xrender.
Check out the skia bug in Firefox for more info.
Skia mostly works now in the latest ff and it is FAST with far lower CPU usage than Cairo.

oh, i thought you meant just alpha blending and such
ye doing text in openGL can be way faster with better results
idk about 3x3 matrices thou
guess you dont have to use them for flat text

I tried the GLES version of KWin (4.11.6) with this driver. It works. But there's some junk rendered behind transparencies/blur and KWin says that eglPostSubBufferNV is not supported.

The whole output of kwin_gles is:
