The screenshot of the observed articats with 4K content

The problem is observed on RaspberryPi 3 B+ platform when the user tries to play the playback which has 4K resolution (in this case is 3840 × 2160).

Step to reproduce (on RaspberryPi 3B+):
1. Open reference dash js player: https://reference.dashif.org/dash.js/v4.1.0/samples/dash-if-reference-player/index.html
2. select playback: https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd (Streams->VOD->[DASH-IF] SegmentTemplate/Number, live profile, 250kbps up to 15Mbps at 4K.)
3. start the playback (click 'Load' button)
4. wait a while when the playback switches to highest representation (4K)

The artifacts on video playback can be seen instead of proper video. The screenshot of that case you can find in attachment.
