Unaccelerated compositing

These are screenshots of KDE on my laptop, with KWin's XRender composite manager running.

The thing is, there is no hardware acceleration here. In these screenshots I'm using the vesa driver (with shadow framebuffer), with 915resolution to get my screen's native resolution.

And it is entirely usable. In fact some effects, like Resize, are faster than with hardware acceleration. Not as fast as OpenGL compositing, and it is a bit buggy, mind - Resize has trouble scaling some windows to the correct proportions - but seriously, what does this say about the state of 2D hardware acceleration on Linux?

Re: Unaccelerated compositing

When I tried Xrender under KWin, minimizing a window took about four seconds, switching workspaces slightly longer.
