Ah I missed that comment, yes file a separate bug for that please, and assign it to me directly from the new bug screen.

I need to discuss this on the upstream xorg-devel list, in a way it is more of a feature then a bug really, the problem is that with the xserver running as user it cannot access shared-memory segments created by other users, such as the root user. One could argue that this is a qt/kde bug. I've written MIT SHM code in the past, and one should check the xshm-attach succeeds (it will also fail when running over the network) and when it does not fail, qt/kde should fallback to not using shm, which it clearly is not doing.

So now the question to discuss upstream becomes if we can do anything to make shm work in this case, or if we simply tell the qt/kde guys to fix their stuff.
