In principle, everything that used to work is supposed to work still. :-)
But it will be easier to track down the problem if you post code. If you
don't want to do that, you are probably the best person to track down the
problem. For that I'd recommend setting up the Haiku source tree on Haiku,
placing a link to the generated libgame.so in your applications ./lib
folder and start adding debug output to the problematic API implementations
that you use. Then your application will run your modified libgame.so with
the debug output and you are hopefully able to track it down. The "complete
freeze" sounds more like your BDirectWindow is blocking the app_server. But
if some media_addon_server realtime thread is caught up in a loop, it may
also look like a complete system freeze. Usually, you should still be able
to press F12 to enter the kernel debugger.

Mhhmm yummie! Screeching tyres... sounds fun! :-D
