I am trying to get 3d working with rpi4 1gb with latest alpha 9.2/kodi 18.3 (LibreELEC-RPi4.arm-9.1.001.img.gz). The output image does not look like SBS or OU, the image does not look "blurred" and the connected projector is not picking up the signal as 3d. It looks normal, but the subtitles are displayed twice next to each other.
Is the 3d part already working in alpha build? If so, what settings should I use?
How can I debug what is happening?
