Yes, at least for certain combinations of X server and graphics card
driver. Also, the combination of Emacs and Gtk+ seems to trigger a
codepath in the display driver that is especially slow, even more so if
scroll-bars are switched on. On my RV350-based AGP card this makes
Emacs' display updates about 80x slower than usual and I can assure you
that this is very noticeable (and annoying).
Regards,
Achim.
