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.

These GPUs are no longer supported by fglrx so I couldn't verify if it was strictly a driver issue or if there was some error in our program code. However, the problem cannot be reproduced with a Radeon HD 4670 and the open source driver (or fglrx). Nor can it be reproduced with Intel GPUs such as the GMA 950 and above. The bug manifest itself in the Unity Dash. When an action is performed to show more icons in the dash, the rendering does not happen. Elements of the Dash only appear after the mouse moves over them, but this is the result of Unity refreshing the rendering. Some elements of the dash also disappear. This make me think that clipping could be involved. Unity makes extensive use of opengl scissoring.

Rather than passing a null region to glScissor, we give the clip area a 1 pixel width.

It hangs after logging in. Could you possibly make a simple OpenGL test case reproducing this bug? It shouldn't be hard.
