This does not work with XVesa, just with Xorg.

Download this file:
http://dotpups.de/dotpups/XServer/transparency-demo.pup

Add these lines to your /etc/X11/xorg.conf

Code:

     Section "Extensions"
             Option "Composite" "Enable"
             Option "RENDER" "Enable"
     EndSection


Restart X.

In a console, type
xcompmgr -a &

Now Windows should move faster, also scrolling works faster.
But that might depend on the Computer.

Stop it with the command
killall xcompmgr


Advantage:
This solution is simple.
So it is worth a try, if you have problems with the other way by using DRI-Kernelmodules, as described here:
http://www.murga.org/~puppy/viewtopic.php?t=5244

------------------------
xcompmgr also can be used to draw nice shadows around your windows.
To activate shadows (what is much slower), try
xcompmgr -C -c -l -14 -t -14 -r 15 -o .7&

Try different values to change position and look.
try xcompmgr --help for details.

Attention:
In JWM(0.2x), the shadows will throw thousands of error messages.
This leads to a crash after half an hour or so, so just use it with Icewm, Enlightenment or others.
I have not tested it with JWM 1.x.
Maybe you can avoid the problems with:
xcompmgr -C -c -l -14 -t -14 -r 15 -o .7 2>/dev/null&
This might avoid that the textbuffer fills with useless errormessages.

Mark,
Could you explain the difference between those two?
For example, if I just had the RENDER extension, not the Composite, what would that do? any speed improvement?

Smile Mark can you highlight or move to the top your recommendation for only using with Icewm or Enlightenment

I tried it and was going to report no difference (but then I am just using JWM) Embarassed be interesting if it works for our Window tinkering Puppys

you need composite.

The render-extension just is needed for some other special effects like transparency (in addition to xcomposite).

I made a Dotpup, it includes xcompmgr 1.1.2, transset, and a small Xdialog-based program to set windows transparent and activate shadows:
http://dotpups.de/dotpups/XServer/transparency-demo.pup (56 kb)

Install, run "run-transset" from a console or the Dotpups-menu.

It will check, if your system supports it, and give tips for activation.

Lobster, maybe on slower machines you will feel a difference?
