FamiTracker
I clicked around on the pattern field to scroll around while it was playing when this glitch happened. I came across this on v0.3.6, but it works on v0.3.7b too.
Looks like that the memory space of the effects-counter variable (for the first channel) were corrupted in a strange way. Maybe it's a problem of your RAM/OS. That never happened to me.
EDIT: Actually, seems to be that the Window slider value has been corrupted. On the image, the noise channel is over the triangle channel, the DPCM channel is over the noise channel, and so on. Weird.
Could you, please, tell us the steps to reproduce this behavior?.

I'm not exactly sure how it works, but this is all I know so far: The FamiTracker window needs to be small enough so that you can scroll horizontally. While a song is playing, click around near the right edge of the pattern field to scroll it around. Sometimes the glitch happens when you do it. It clears when it moves into a different frame.
Also, it seems like it only works when scrolling to a certain channel.

I've actually noticed something similar in FamiTracker 0.3.0 when it involved changing pattern numbers for the rightmost channel of the screen. But I shrugged it off since it didn't really affect my work (it only affected one channel, unlike your case).
I know that there are some 32-bit programs that don't work as they should in 64-bit OSes (usually anti-virus software & a small number of programs that take advantage of certain drivers). But I'm not totally sure about FamiTracker (after all, it's such a small program & I'm sure you have a hefty amount of RAM on your system to compensate for its use of audio drivers).
Or could it be graphics drivers? I mean; the tracker's display is constantly in motion when you're playing the tune & moving from line to line.

This is strange as that shouldn't happen and I can't reproduce it myself.
The glitch itself is nothing to worry about though, it's caused by the tracker copying parts of the screen instead of redrawing it (to speed up drawing). No problems with drivers and such. However it should detect when a full redraw is needed, for some reason that fails here.
Wow; that was an interesting display glitch.
