I've already given up hope
..that is what I got on all images after 20190522: either few seconds showing and then frozen video(audio still working) or white screen with working audio.
Last Image which worked for me quite good(streams and local files work) is that: LibreELEC-AMLGX.arm-9.1-devel-20190522171931-a41fdf1-box.img.gz
Same for me, that one works seems to work okay on the WP2.
Obviously HDMI bitstreaming is still WIP, and the standard WeTek mutliboot is bypassed but it's getting there.
