In your command line, you do not specify a colour space. Older FFmpeg by default degraded colour information by choosing yuv420p even if the input format is rgb, newer FFmpeg chooses an output colour space that allows for maximum compatibility with the input colour space (see tickets #1426 and #1517).
I suspect it will work fine with -pix_fmt yuv420p - please test.
Please post complete, uncut console output together with your command line.
Please consider using git bisect to find the change introducing the regression.
