------- Additional Comments From damjan.jov@gmail.com 2006-07-11 13:07 ------- Although I couldn't open the MClass Mastering Suite Combi (missing file?), I tested the corrupted play button. I've just submitted a patch for the bug I think was causing the regression to wine-patches. Bottom-up DIBs were being misdetected.
Reason 3 makes heavy use of client-side DIB copying. Further work should make it even faster. Thanks Willie, now I've got a good app to test my work on.
