IIUC, "Fixed" is a bitmapped font while "DejaVu Sans Mono" and even
"Courier New" are TrueType or OpenType scalable fonts. That could indeed
make a difference. Try running GTK2 gvim with
set gfn=Misc\ Fixed\ Semi-Condensed\ 13
(which ought to be the same as in your Motif gvim) and see if it doesn't
redraw much faster than with DejaVu. (Of course, Fixed is uglier. You
can't have your cake and eat it, or for Dominique and François, the
butter and the cash for the butter.)
Best regards,
Tony.
