They flicker not only when being used, but apparently for any redisplay that happens, no matter how small (e.g., insert a character at the end of the buffer, and the scrollbars will flicker), and indeed, flicker quite a bit even if you're doing nothing! I can't really tell exactly what's happening, but it looks like it's simply redrawing the whole scrollbar at every opportunity. I tried to use as standard an environment as possible, e.g., `emacs -q', no .gtkrc-2.0 file, no X resources. The flicker is even more noticable with pixmap themes, presumably because they're slower to draw, and often use more contrast. It's a debian-unstable system, which Is this a known problem? Is it solvable? I don't see anything like this with other GTK apps, so I guess it must be emacs. BTW, libgtk is version 2.2.1, emacs is today's CVS. Thanks, -Miles -- We live, as we dream -- alone....
