Hello! I'm trying to do something stupid, and I'm stuck, and I'm wondering if anyone with a bit more experience could perhaps provide a hint as to what might be going on.

The stupid thing is that I'm trying to get the version of QuickTime that comes with Mountain Lion (10.8) to work on Mavericks (10.9). The Mountain Lion QuickTime works with rtsp live streams and supports many more video formats, and I greatly prefer QuickTime's interface to other players.

The crazy thing is, it actually 95% works! I had to do some install_name_tool trickery to link up some Mountain Lion frameworks, but I had almost everything working within a couple of hours. Almost everything.

When I try to play a video, everything looks (and works) fine:

But when I try to play an audio file, it looks like this:

Whereas it's supposed to look like this:

The weird thing is, there aren't any errors in the console—QuickTime appears to be completely unaware that there's anything amiss. The issue is also entirely cosmetic—the invisible window can be moved, resized and minimized as usual.

I'm not expecting anyone else to have experience doing weird hacks with QuickTime, but I'm wondering, has anyone with more proper app-development experience ever come across something like this? Where an app appeared fine in an older OS, but the window background was suddenly invisible after updating. If I had an idea of where to look, I could poke at things and possibly inject some code...

Thank you so much!
