Hello,
I face the similar problem with this Netflix plugin + RPi3b + Kodi18 + Raspbian Buster.
With Hyperion active if I play Netflix video with 1080 resolution the HDMI connection drops, and with 720p screen starts to flicker. If I stop Hyperion then video plays perfectly fine.
Now I have reduced the resolution to 480p in Input Adaptive stream setting and video plays fine with hyperion active.
Hey there,
yes works fine w/o hyperion.
Overclocked the Pi and it seems to work fine now. Apparently decoding DRM from Netflix and Hyperion was too much ...
Could you please share your overclocking setting for RPi3b+ .
