gvim does resize in steps - lines and chars.

Firefox in Ubuntu is just a mess, particularly the javascript engine. Run 
up a cpu usage viewer and watch FF take off when you do something. Heck 
it even takes a few seconds to close @ 80% cpu!

kde4.3? Seems like our next hope.

I've not started following the dev chat on this, but I hava feeling that 
there are some big issues with kde4's graphics architecture.

I've been running KDE/Openbox today and it has cured a huge number of 
issues. I've never used it before, and I'm pleasantly surprised. 
Amazingly, even kmail hasn't crashed today. It usually crashes about ten 
times a day. Best of all, I've got my GL screensaver back :-)

Seriously, though, it runs far less bg tasks, and consumes far les cpu, 
thus the machine runs a lot cooler. And it's way faster for the heavy 
duty task I have to do.

I think I'm going to persevere with this set-up and see how it goes. I 
highly recommend giving it a go.
