output changing from channels until the problem occurs.

With the current Mesa update I experience the following: 

during playback of HD satellite video channels (e.g. Arte HD) the playback
presents (at times, this is not a perfectly constant behavior, resizing the
window, changing channel or fullscreen or exit fullscreen mode may help to
stabilize the picture) as follows:
flicker, some image appear nearly as still image. 
- sound is normal
- no HD channels are normal
- HD channels may also appear "green" 
- when registered to a mt2 file the output is perfect. 

Hence only the playback function is touched by this. 

Signal strength is good. 
Output in Kafeine on CLI as follows:
(see attachment)
However this should correspond to the beginning of the flicker:
