Thanks for testing the patch, it requires some tests and also to check what happens for bit count higher than 8 so it will take some time to be merged in wine.
Argh, I'm sorry it turns out my test was using another library from winetricks I forgot to uninstall. The library was installed in the system32 folder so it fooled me into thinking I wasn't loading anymore of the copied Windows libraries. It should be clean now though, only use Wine libraries and your patch.
Any who, in this test the main AVI from HL is a lot better than default. There's a bunch of these gray areas on the background. Which is interesting because some other AVIs used in mods do this on Windows and in Wine.
I encourage you to keep going as if you figure out why this gray issue occurs, I think the AVI will look perfect.
