Hi, I'm experiencing extremely slow typing and screen updates
on Debian wheezy (Xfce4 Desktop with "Redmond" theme). Sometimes
geany can barely keep up with normal typing speed.
My impression is that Geany emits an excessive number of X server requests,
even for trivial editing actions like moving the cursor. Using
xtrace --relative-timestamps /usr/bin/geany
I observed that moving the cursor (by a single line or column) or typing
a single character often emits several hundred Render requests. Now I'm no
expert on the X protocol, but my feeling is that Geany redraws large parts
of the edit window unnecessarily.
The problem exists with simple text files and syntax-highlighted files.
It seems to get worse with long editing sessions.
Note: maybe related to #778
