Fast Forward with new Video Player

I have a problem with the new video player in Kodi Krypton on my Sony X850D (XD85) running Android TV 5.1.1. SoC is a MediaTek MT5890 with dual-core ARM Cortex A17.

I am playing a TransportStream with H.264 1080i and AC3 audio (via passthrough) via MediaCodec Surface.

When performing fast forward there is only a still image displayed. The image never ever gets updated, giving you no indication of where you are in the video. No matter whether you scrub at 2x or 32x. When resuming playback (1x), it takes about 10-15s until the video plays again.

In Kodi Jarvis there are frequent updates of the video image when performing fast forward.
