Sometimes doing things that no sane person would do gives insights.
Othertimes, it just hurts more.

For some odd reason, it seems to be behaving exactly the opposite of how it
was behaving initially as far as "Copy To Texture", but maybe I had it in a
different state when LyX started up.  The following tests were done by
setting the given settings, loading LyX, opening a 100+ page document,
scrolling up and down a bit, and then starting a new paragraph and banging
away like a mad monkey and seeing how well it keeps up.  I also looked at
scroll speed and ended by typing a sentence to see if it was in a "losing
keystrokes" state.  If it couldn't keep up, it was marked "Slow", if it
kept up, it is "Fast".  Sometimes, the performance would change and get
slower or faster, and I tested everything again when this happened.
Sometimes it would get to the point where it would lose keystrokes - it
actually looked like some sort of buffer overflow.  Once it loses a
keystroke, you have to hit a key to get the one it lost.  I marked Bug
#1329082 <https://bugs.launchpad.net/bugs/1329082>  as a duplicate as this
is definately what I was seeing before.

I'm 80% sure these problems don't appear on the binary ATI driver, but I'm
not willing to re-install it to find out just yet.  Getting rid of it was
like pulling teeth.

Most Consistent Results:
----------------------------------
Copy To Texture   ON        ON    OFF    OFF
use_qimage           false     true   false    true
Speed                     fast       slow   slow   slow

The only winner seems to be to have qimage to false and copy to texture
on.  Anyone else want to verify this?

Title:
  lyx 1.6.x impossibly slow

Status in “lyx” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: lyx

  I am using lyx 1.6.1 on Ubuntu 8.10. This program used to be my do-
  everything software, but it has become unusably slow.  That is,
  keystrokes are even delayed in displaying when I type.  The rest of
  the system is fine, and LyX didn't used to have such a problem. I'm
  not sure where to start in debugging this.

   apt-cache policy lyx
