Slow Scrolling = (Ubuntu 64-bit + Xinerama + CodeBlocks);

Hey guys,
First off, I've got to say, Code::Blocks is fantastic.  Unfortunately, I've been having some problems with the scrolling speed under Ubuntu.  I've seen all those slow scrolling threads around here, and I could be wrong, but they don't seem to apply to this particular problem.

My System Specs:
Laptop
Processor - Intel Dual Core 2 - 2.2Ghz
RAM - 1.5G
Video Card - NVIDIA 7600 Go
Video Card Drivers - NVIDIA Restricted Driver Version: 173.14.05
Operating System - Ubuntu Hardy 64-bit
Using Dual Monitors

My Code::Blocks Version:
Grabbed from SVN today (7/1/2008) and compiled with wxGTK 2.8.8.

Here's the problem:
When I'm using Xinerama for the dual monitors setup, Code::Blocks starts scrolling extremely slow.  The logs window scrolling speed is completely fine.
The thing is, whenever I'm using Code::Blocks and using TwinView for the dual monitors setup, the Code::Blocks scrolling speed is completely fine.

I love using Xinerama for my dual monitor setup, and would rather not have to use TwinView.  Is there a way to get the scrolling speed to work ok in Xinerama?

Here's an update:
I switched from Ubuntu 64-bit to Ubuntu 32-bit and I am now using Xinerama with the same NVIDIA drivers above (173.14.05) and the performance has SIGNIFICANTLY improved.  I can actually type at a decent speed, scroll fast, etc, etc.  So, it seems to be the 64-bit NVIDIA Xinerama causing a problem.

In short, it's still best to use TwinView over Xinerama, unfortunately.  Bad Xinerama, bad.

Thanks for the info. I noticed the same problem on my machine (slow scrolling). I switched from Xinerama to twinview an the problem has completely disappeared.
