Hello,

I just experienced a bad problem with xfce's Terminal behaving very 
slowly in xfce 4.4.2 on openbsd 4.3 whenever it was resized, or had to 
be re-drawn (ie, switching workspaces).

In xorg.conf, I put this:

Section "Extensions"
         Option  "Composite"     "Disable"
EndSection

(If you don't already have an xorg.conf, then try running X --config to 
make one)

And that fixed it for me, now its nice and fast. It appears to be a bug 
in Terminal.

Cheers,
	Josh
