Comment 21 for bug 859723

Same here, irrespective of whether Opera is installed or not. In my case the problem
always occurs sometime after login on battery power and sometimes (but less frequently)
on AC power. I ran 11.4 before on the same machine, absolutely problem free.

I have tried a all the suggested workarounds and none of them works. I could 'live' with
the 'appearance issues' but for me the most critical part is that the power indicator
stops working when the error kicks in. In turn, it happened on several occasions that
while I was running some urgent jobs on my laptop the computer just shut down.

Now, given its low priority is there any hope for a fix or is a downgrade unavoidable?
