Since I updated to the new playability branch, the gui's background pngs aren't transparent anymore. I tried to fall back to an older version to compare them, but of course this isn't possible anymore. (because the old playability branch has been deleted). I guess it has something to do with patrick's texture-handling changes. Or could it be something I have done lately? (Well, actually I've just loaded some png's into my widgets - that's all).
Any ideas how to solve this issue?

Solved.
