The QsciScintilla editor is responding slowly (takes 1-2 seconds to change after keypress while line number display changes immediately)

I can reproduce this on:
- one computer with Nvidia graphics (64 bit ubuntu 10.04)
- one computer with ATI graphics (64 bit ubuntu 11.04)
I can NOT reproduce this on:
- one laptop with Intel graphics (32 bit ubuntu 10.04)

So, I tried this example code:

I can run it without any delay on my affected machines.

I tried removing the 3D view, the python lexer, but with no change.

This is a wild guess: I wonder if the editor gets interfered with the QT main loop or this has something to do with the UI builder.
