Could all who are interested in this bug/thread please consider the following "bug" which I think is related to why LyX is much slower on figure floats: http://bugzilla.lyx.org/show_bug.cgi?id=4002 "The figure float box is roughly the full width of the window, but in fact it is changing a small amount with every keypress. This causes the figures to move because they are in a centred paragraph." I'm not keeping up with what X with and without DRI are doing. With DRI, perhaps it's supposed to locally blit from one place to another. However, who knows how good or bad the s/w implementation is, it might have been faster to send it again from the source buffer. Could the 16/24 bit issue be related to a format conversion between LyX/Qt4 and the X display, which is skipped in one case but not the other? Have fun, Darren
