Description adikurthy 2012-09-02 18:27:55 UTC
After activating the effect for a given window, the thumbnail updates are not happening, the thumbnail even disappears if another window is moved to it's area. It only updates if the attached window updates for some reason.

Reproducible: Always

Steps to Reproduce:
1. Enable Effect
2. Toggle it for a window.
3. Start move windows around
