To reproduce:
1) Open a complex lyx file with many math insets, macros etc. (e.g.
http://www.csse.uwa.edu.au/~john/drafts/Thesis_Background.lyx, or just
create a new document and fill the screen with "$x$ x", where $x$
represents math-mode x)
2) Hold down X (or any other normal key) for a few seconds.
3) Note that LyX cannot keep up with typematic rate, so X's will
continue to appear a couple of seconds after release key.
That shows up also without maths: I have put ~3000 chars in a single
line without breaks. Now when I'm in full-screen mode (1440x900) the
cursor moves very slowly (only ~10 positions per second), so cursor
movements are buffered and I can see one of my 2 cores going 100% from
the monitor applet.
When resizing to a smaller window size (800x?) it returns to move
quickly as usual.
Anyway, not really a realistic use-case :-).
With your thesis, I can see slowness only when causing a scroll up and
down of the document (this is already evident [and annoying] with the
UserGuide), otherwise movements don't seem slow if the cursor simply
moves on the visible screen without causing any scrolling.
Also disabling on the fly spell-check and instant preview doesn't help.
