What I find quite interesting is that when an icon is corrupt (for example, my wireless network icon is half-obscured by half of the CPU temperature icon shape), and the icon is subsequently modified (e.g., I disable and re-enable wireless network causing the icon to animate), the only part of the icon redrawn is that part NOT obscured by the incorrect half of the CPU temp. icon. In other words, only the currently correct bit of the icon is redrawn and the bad bit is always bad. Even when I totally remove the CPU temperature from the panel, the wireless icon is STILL corrupted with half the temperature icon. This is pretty strange. I find it hard to think of a programming scenario which would allow this. It's almost like the buffer for the icons is the right size, but the animate/draw code somehow thinks the width of the icons is smaller than it actually is. So when the icon buffers are blitted to the panel, they're the correct size, but we always get whatever is in the icon bitmap buffer. And since the icon only ever draws to a smaller width than it actually is, we always have the corrupt bit. That's my guess, anyway. So I'd be looking for some corruption of the icon width, not some sort of incorrect overdraw of the icon. My guess is that what's overdrawn is actually what was previously in the icon buffer before the width got corrupted. Just a guess.
