Hi,
there's an issue with 3D playback.
Description here:
#17251 (3D-Playback not working)
– Kodi - TRAC
Fritsch provided a patch to sort out this issue.
Resolution: Do not switch resolutions when in 3D (only refreshrates) · fritsch/xbmc@b6cc33e · GitHub
Is this the right place to ask for implementing this patch / asking for a LE testbuild?
