--- Comment #2 from LoneVVolf lonewolf@xs4all.nl --- After seeing marek reply I experimented a bit with PP_DEBUG and post processing filters. Half of the error messages comes from pp_jimenezmlaa filter , the other half from pp_jimenezmlaa_color .
disabling those filters through driconf does make the corresponding error messages disappear.
The error messages started recently, want me to try bisecting to find out what caused them ?
