I now noticed that I also get some corruption when I don't use presentation
mode. It just takes longer to trigger the problem (by opening several PDFs and
scrolling in them) and the screen is not that much garbled. Last time it
happened only some icons in KDE were painted badly when the mouse hovered over
them. Compositing was enabled (only XRender, not AIGLX) at this time.

I don't know much about GPU programming but to me it looks like something goes
wrong when transferring textures from GPU memory into RAM and back.
