Well, I use pixmap gtk+ themes all the time, together with the cvs version
of e. You can compare with Windows9x in redraw times by saying that GTK is
slower to the point of noticbly lagging behind. This is prolly due to the
redrawing of the pixmaps, but it should be investigated for possible

Another thing to notice though is that the loading of applications is
often slower than in Windows, GMC takes about twice the time that Explorer

Finally, I've noticed that GTK does strange things:

1. Sometimes if you click to bring up a menu and move over the *expected*
location of the entry (i.e. before it's had time to actually draw the
menu) and then click when you see it (lag of around a second?) GTK doesn't
pick it up - you have to bring up the menu twice to have the entry pick up
mouse events.

2. When an app such as GMC which draws many gtk areas/widgets loads, there
is a noticable flicker effect as everything is added to the screen. Maybe
it would be better to stop the window from being drawn until the display
is internally finished and can be drawn from memory? This appear to be the
way Explorer does it (at least, Explorer does have a noticable delay with
no disk activity before instantly appearing on screen - presumably sorting
out directory contents before appearing).

Something for the Window Managers which I find really annoying - when I'm
using GIMP, often windows will appear below the current mouse pointer
location. By change this is often near the bottom of the screen, and
dialogues will pop up with their bottom-halfs off the bottom of the
screen. This is true though for many applications - if I could tell the wm
to always initially display windows fully-on-screen, then be able to
partially drag them off-screen later this would be a big usability
improvement for me.
