[Texmacs-dev] qt TeXmacs is deadly slow

[Sam Liddicott]

With --enable-qt I'm finding teXmacs will go to 100% CPU for a second or 
more when I do mild things like insert a blank line near the beginning 
of a medium document. (Even with Document, Page, Type, Automatic).

The delay is the pagination changes, and is very short at the end of the 
document.

As an example, try importing this into TeXmacs: 
http://en.wikipedia.org/wiki/Gun_laws_in_the_United_States_%28by_state%29 it 
is about 600K long in the html

Pressing ENTER near the top of the page uses 100% CPU for about a 
second, inserts the line and then paints a corrupt screen.

I compiled non-qt and everything is great! (except the stinking file 
dialogs).

Does qt support non-event-loop based painting? (If that's the problem)?
