Just to say it clear as there are some rumors are floating around:
CE tried to work 3D out last 2020/07. There was no big interests and the changes did destabilize the kernel and kodi. So we dropped the changes and did put it on hold. We did not waste any thought on 3D the last 4 years - as the know factor is, it’s EOL. It’s not that we are already working the last years to get it working, sure not!
So this will be a new, last start to maybe implement the feature. We will see…
