Bug 316033

Curiously, switching from the non-decoration state back to a theme like KDE 2 or modern system corrects the issue. I am then able to switch between themes that would normally trigger the bug.

So, for example:

1) Switch to air-oxygen
2) Decorations disappear
3) Switch to modern desktop
4) Decorations are back
5) Switch to gaia-recycled (no issue)
6) Switch to air-oxygen (bug reappears)

I do not think it is limited to GHNS themes -- perhaps those that use transparency? 

Reproducible: Always

Steps to Reproduce:
1. Switch to a theme like air-oxygen
2. Switch to another theme like gaia-recycled

Actual Results:  
Window decorations disappears

Expected Results:  
Window decorations should switch cleanly.
