#98 Ultra-slow editor display in 2966 on Windows X server
Hi there,
at work I quickly tested revision 2966 from SVN today. The setup there is: gap5 lives on a Ubuntu 9.10 server, I am on a Windows machine and connect via X-Server running on Windows ("Reflection X") to the Ubuntu server. Connection is crypted and compressed.
Now, with gap5 from the "staden-2.0.0b9.x86_64" binary package, everything works as expected. However, with gap5 from revision 2966, the contig editor is unusably slow: one can see every line being built one by one. Scrolling is impossible.
I made a wild guess and tried to see whether the code assiciated to the message "sheet_font is proportional - picking a new font" was responsible but even commenting out the whole font definition block there in "init.tcl" I did not get lucky.
Any idea?

Ok 2nd attempt at replying. grrr.
Please check which version of Tcl/Tk you compiled against. I think the b9 binaries were probably 8.4. Gap5 works with 8.5 too, but I know 8.5 has completely new font handling code to support anti-aliasing. This may perhaps be triggering some bug or inefficiency with your X11 server.
It's also worth experiment changing the default sheet font. Just commenting it out likely pick something inappropriate instead. It needs something like "fixed" or "terminal" perhaps. Choosing a name that works on all platforms is rather tricky!
