I play dota2 for many months already and never has this problem. This happen when the new patch come (14.9.2012).
When i restart my computer, the problem is fix (PURE LUCK). Today, I has the same problem again.
My graphic card is up to date. I tried VERIFY INTEGRITY OF GAME CACHE and reinstall my dota2. Nothing work.
