I don't know if others have narrowed the culprits for the severe window jitters or chopiness, but both the Oxygen and QT Curve themes are those in which the problem is severe. I am using Sculpture and once I switched to that, the jitters went bye bye.

Can anyone confirm that the Oxygen and QT Curve themes are the problem or reflect the problem with respect to the window jitters/chopiness?

I am using Platform Version 4.5.90 (4.6 RC1) via Mandriva Linux 2011 (Cooker) 64 Bit. I update it each night to snatch the latest files.

I run a nVidia 580 reference board and OpenGL with the following settings:


Window Decoration: Nitrogen
GUI Style: Sculpture
Fine Tuning: Very High CPU & High Resolution - 4.4GHz @ 1920 x 1200 x 32 @ 59Hz

Compositing: Active w/ Shadows and Various Animations enabled (checked)
Scaling: Smooth
Functionality Checks: Disabled (checked)
Direct Rendering: Disabled (unchecked)
OpenGL Mode: Texture From Pixmap
VSync: Enabled (checked)


Desktop Effects Enabled:

Fade Effect
Highlight Window
Login
Logout
Sliding Popups
Tasbar Thumbnails
Desktop Cube Animation

I am using the OEM drivers directly from nVidia as they provide for many options to be changed. The latest version is: 260.19.29 dated 12/09/2010 with the README dated on 12/17/2010 to reflect changes.

I also have the same setup running via an nVidia Quadro 295VS GPU which provides the same performance with respect to the window jitter issue.
