--- Comment #4 from TouchMyBox pzoned@gmail.com 2012-08-29 18:15:37 CDT --- It is my educated guess that this is the same problem which affects other Source Engine games. In the source engine, if you do not take advantage of multi-core rendering in the current build of wine, then source engine games run pretty much without any rendering glitches (with the exception of minor stuff like black blotches on the textures of health and ammo pickups in TF2). As soon as you enable multi-core rendering however, you get a nice FPS boost, but at the cost of lights sources penetrating walls and wonky text rendering. Dota 2 takes advantage of multi-core rendering by default, and of course the first problem doesn't exist in dota because there are no walls, the text still rendering wonky.
This isn't a dota-specific bug, but rather a bug with the multi-core renderer in the Source engine.
