KDE SC 4.7 May Utilize OpenGL 3.x For Compositing

[energyman]

or: Qts Xrender implementation follows the spec and Intel and Nvidia are broken.

Of course it follows the spec, but it doesn't mean it does so in a way that makes sense and is able to perform well given current GPU hardware. See http://bugreports.qt.nokia.com/browse/QTBUG-7255 for example.

So I guess this means that if the driver doesn't handle it the current (legacy) mode will be used. And if even this isn't posible there is still XRender mode I guess.

Also afaik VBO's are a pretty common extension even if the drivers don't have a full OpenGL 3.0 implementation. So this shouldn't be an issue, I think...

VBO = OpenGL 1.5
FBO = OpenGL 3.0

So assuming VBO's are really all that's needed, I'd assume classic Mesa drivers with KMS are sufficient Right Now (tm) since they advertise GL_ARB_vertex_buffer_object.

Yeah, and the KDE developer was talking of VBO's, not FBO's.
