ofxOMXPlayer does not scale to screen - any more

Hi all,

Sorry, I had put this on the wrong category. So this time on the right spot:
On my newer Raspberry installations (Jessie, OF 0.9.1 or 0.9.2) ofxOMXPlayer does not fit (scale) the videos I play to the screen any more, while omxplayer (called from from command line) does.
I am using non-textured mode, old code that behaves differently on older systems.
It also happens with example-basic and example-direct-mode.

Is there some new setting or switch I am missing?

Thanks in advance!
