When rendering the Unity dash icons are frequently missing from the rendering. This video is a good demonstration of the problem: https://launchpadlibrarian.net/68813544/unity-bug.ogv
This works on r600g, nouveau, i915 and i965, so it looks like it's a bug somewhere in r300g.
The dash rendering uses FBOs and ARB shaders, with glscissor for clipping.
