Comment # 31 on bug 1139791 from Stakanov Schufter

Created attachment 810673 [details]
effects of the radeon problem on e.g. vidcutter

O.K. after the latest workaround kaffeine works again by using vaapi as I see. 
Unfortunately vidcutter is still broken. I have some more info I think. 
I get from console:
entropy@silversurfer:~> vidcutter
radeon: The kernel rejected CS, see dmesg for more information (-22).

I will post in attachment a screenshot how the app presents now. I will then
also join dmesg. 
Hope that helps. 

(P.S. thank you for the work around in kaffeine).
