Thanks Raster, that was some very good spotting.
I said tight loop becaues it keeps my CPU awake and warm enough that the fan
was running constantly.
I had an older intel driver and e18 before, and this just did not happen
(with the same clients). I'm trying to think of what could have changed.
Also, I still don't understand how e19 was using almost double the CPU when
OpenGL rendering was used as opposed to software rendering.

So I think I found the problem. When I have mplayer running, e19 goes into
that mode.

Can I check if that is the case?

Aaah, very good suggestion. Yes, I have the new pager. Let me see if I can
turn it off next time to see if that helps.
Or can I just tell it to update once per second or less?
Thanks,
