So, once again, I fell to the allure of the window decorator emerald. Where, just like the first time around, (I know I know) upon attempting to back out of emerald to the safety of compiz I'm faced with a problem.
Seemingly after several minutes or after opening Chrome any window that isn't maximised has it's borders removed (so there's no close, minimise and maximise etc buttons). I can get them breifly back if I reload compiz via fusion-icon. After a brief chat on IRC it appears compiz is crashing. Here's a pastebin log of me running compiz via terminal.
I forgot my two vows of 'Never bother using Windows applications via wine or a VM' and 'Thou shalt never not use compiz'.
