Well, today I decided to give Steam on linux another try, since it should have matured quite a bit by now. TF2 used to run back a few months ago in Linux Mint 15, although with a 70% performance reduction from Windows.
Core i5 3210m
8gb DDR3 Memory
Intel HD 4000 - Intel Mesa Driver
LM16 Petra - RC1
Both TF2 and Day of Defeat:Source start up. You can see the menu items, although the backround is black, and the buttons are not rounded and are glitched. If you log into a server, there is nothing visible except for wireframe player models on a black screen.
This error shows up in Console:
Error: Material "debug/debugluxels" uses unknown shader "DebugLuxels"
Error: Material "___fillrate_0" uses unknown shader "FillRate"
Error: Material "___debugnormalmap_1" uses unknown shader "DebugNormalMap"
Error: Material "___debugdrawenvmapmask_2" uses unknown shader "DebugDrawEnvmapMask"
Error: Material "___debugdepth_3" uses unknown shader "DebugDepth"
Error: Material "___debugdepth_4" uses unknown shader "DebugDepth"s
I could not find much information on this issue, nor anyone else with the same symptoms (wireframe player models)
Here is some more diagnostic info:

Looking forward to any sugestions.
