Pardon the cross posting here, but I nearly hit with some tumbleweed on the Linux forum. My waveforms aren't being drawn correctly on Linux. The first few times I call AudioThumbnail::reset() and redraw it's fine. But after that it all goes south. I just don't know where to start debugging if I want to find the route of the problem(unique to Linux). More details and fancy graphics can be found here:
Hopefully someone can at least point me in the right direction. I'm happy to weed through various code, but for now I'm stumped.
