I thought I bugreported this, but maybe not. Or maybe it just hasn't been fixed yet.
Either way, if SL is minimized, my log gets flooded with this:
2005-03-04T03:56:56Z WARNING Setting subimage on image without GL texture
And by flooded, I mean it outputs about ten to twenty of those per second. SL doesn't seem to completely comprehend what being minimized means... which is unfortunate. Windowing isn't something I like to do (all my window positions get skewed =/).
