Comment 12 for bug 783534

I experience this problem too, although not every time - probably around 50% of the time that I try moving windows between workspaces it works on first attempt, 50% works on second attempt. It's never failed to work on the second attempt. Like Johan I am using Ubuntu 11.04 Classic.

Autra, you asked for a list of compiz plugins. For me it is as following:

General: Composite - Gnome Compatibility - OpenGL
Accessibility: Enhanced Zoom Desktop
Desktop: Expo - Desktop Wall - Viewport Switcher
Effects: Animations - Fading Windows - Window Decoration
Image Loading: Png
Utility: Bailer - Compiz Library Toolbox - Detection - Mouse Position Polling - Regex Matching - Session Management - Workarounds
Window Management - Grid - Move Window - Place Windows - Resize Window - Scale - Snapping Windows - Static Application Switcher

If anyone knows how to create this list automatically, it might be worth sharing the tip!
