I did as well, played for about an hour with no issues. Then I disconnected from the server for a while but left TF2 running. Later I reconnected and the bug (or at least the same symptoms) appeared after 5 minutes. (ahhh nuts!) Exiting (killing wineserver, etc.) and restarting Steam didn't help at that point.. within 10 mins the symptoms always re-appeared.
If I leave myself connected to try and wait it out I always get disconnected (client timed out).
