--- Comment #223 from byteframe byteframe@gmail.com 2012-01-07 15:15:59 CST --- I'm not a CSS player, but I used to apply win98 mode to hl2.exe, so lots of source games wouldn't crash, including tf2, and insurgency (which would crash on start up). I no longer need to do this; I can use winver winxp, and the games don't crash (and might also be running faster).
Hopefully this evidence is not too anecdotal, but it might show that the bug is fixed or ameliorated as a result of recent gdi/dib work.
