--- Comment #7 from Joel Holdsworth joel@airwebreathe.org.uk 2010-01-09 08:24:27 --- I'm not sure what to suggest. My patch fixes a real problem with wine, whereby it would fail to choose the correct colour depth of icon to load on 16, 24, and 32-bit screens. The image that wine would load would effectively be a random guess. This is why Miranda may have worked before.
It might be worth doing some investigation around the problem. I suspect that Miranda's icons are formatted in a way that causes wine to misinterpret their colour depth, but because colour depth choosing was broken 1.1.35, Wine just happened to get lucky with some icons. Notice that even in 1.1.35 not all the icons work. Now that this problem is fixed, it exposes the underlying problem consistently across the board.
