Footnote is extremely slow

"Now" meaning that wasn't like this some revisions before? If so do you remember the revision which changed that?

With revision 50 it was fast and efficient, then I haven't tested all revisions till 60, as soon as I can I'm going to test all revisions between 51 and 59 and report here when this started.

I haven't checked yet because I thought it was a common problem, is it only me who's experiencing this problem?

For me it's no problem, everything runs as fast as possible.

Ok, after some tests I got:

At revision 51 it was still fast as it's always been.
At revision 52 startup remained fast, but switching notebook become very slow.
At revision 53 even startup become very slow.

Which Desktopmanager do you use? Do you have hardware acceleration?

I use unity 3D under Ubuntu, so yes, I have hardware acceleration.

Forgot to say, Ubuntu 11.10

I have a i5 quad core using SandyBridge graphics, and i have indeed the same problem when adding 20+ notes. I guess it is because Gtk just doesnt like it when you show() and hide() that number of VBoxes every time you switch. I'm assigning myself to this as i am the one who caused it, i'm going to think of a nice solution!

After some test I found out these are the two parts that takes a lot at start-up. Both are located in NoteView.vala

First part:

foreach (Gtk.Widget w in get_children ()){
    print ("\nA");
    if (w.visible) //check if we need to show/hide it
         w.hide();
}

Second part:

if (app.selected.category != null)
 foreach (Note n in app.selected.category.notes) {
  if (filter == "" ||
      filter.down () in n.title.down () ||
      filter.down () in n.content.down () ||
      n.tag_area.has_tag(filter)) {
   if (!n.visible)
    n.show_all ();
    showed++;
  }else{
   if (n.visible)
    n.hide ();
  }
 }

Yes, like i said, the hiding and showing of widgets is very slow. You can expect a fix somewhere at the end of this week!

Thanks, I'm glad to hear that, right now I'm stuck to rev 49.

I pushed a fix that made rendering notes significantly faster on my machine, could you please test it (rev 63)? Rendering is still not very snappy, and i guess that is because we are using Granite.Drawing.BufferSurface, which is, quoting the documentation, "designed for usage with large, rarely updated draw operations", and notes are neither large nor rarely updated...

I removed Granite.BufferSurface in rev65, for me it's faster.

To me now it's fast enough to be usable and even better than before.

Faster here too, though the gradient around the note is not very nice, but i guess that is not relevant here. Marking as fixed!
