Nope. After refreshing the display once, it doesn't happen again. I'd say that it happens about, er, once a thousand times that Emacs displays a message, and it's totally unreproducible. I *think* what happens is always that this only happens when I scroll the buffer down and it reaches the end. After the end of the buffer, the bottom of the window should be totally blanked out, but sometimes (if there's an image in the part that should have been blanked out after scrolling), it doesn't happen. So my feeling is that there may perhaps be an optimisation relating to clearing the window after end-of-buffer. But that may be totally wrong, of course. :-) > I've seen in the past redisplay problem with images, but they would > disappear in a fresh session of Emacs, even if I made exactly the same > gestures as the ones which reproduce the problem in a long-running > session.

I'm now running with GLYPH_DEBUG and STDERR to a file, so I should be able to get a trace the next time... -- (domestic pets only, the antidote for overdose, milk.) bloggy blog http://lars.ingebrigtsen.no/
