Hello Reuben.
Thanks for the suggestion. Believe it or not, I had just arrived at that
same solution! I first tried to use GLib.timeout_add(), and that worked too,
if the time was larger than 300 - 400 ms, which is on the verge of annoying.
I then tried idle_add(), and I guess that makes the 300-400ms 'built-in'.
Now, can this visible delay be eliminated? Maybe disabling the scroll
animation alltogether? (it's really visually a scrolling issue) I haven't seen
this problem in Geany (which I believe uses scintilla).
I did a more complete description of the issue on Stackoverflow, because, at
first, I didn't see my question appearing on the mailing list here:
