Right_click_edit_value dialog flickers when window is custom size

[Sam_]

Reproducable since recent compiz updates.
Setup custom window size via ccsm window rules e.g.:
class=Gconf-editor 801x501
Open gconf-editor, navigate through /apps, select any app e.g. /apps/mahjongg, edit a value via right click 'edit key-value', the dialog window which opens flickers as long as it has mouse focus or resizes to normal when moving the mouse a little to the left. (video)

## it doesn't let me add compiz as second project.
