[Issue Report] TF2 stuck

[schakal3000]

When I start Team Fortress 2 from the Steam-for-Linux Client it starts correctly but then it's stuck in a black screen. It still consumes much CPU power and RAM, and in irregular intervals it loads data from my hard disk.
When viewing the task manager I see three processes, all waiting.

Using:
Acer Travelmate 5740
Intel HD 3000
Kubuntu 12.10

This is a known issue, under investigation.

Ok, after the latest update I still have a black screen, but at start I hear the Valve start sound.
Btw: I forgot to add that I'm using a 64 bit system, but with necessary ia32 libs installed.
