Hi all, I just installed the latest Librelec with kodi 18.3 on my Raspberry Pi4B. It all seems to work fine until I try to watch a tv show or movie or any kind of video. I only hear audio but the screen remains black. I tried to fix it with some solutions online. But the options there suggest to change the render method. But, this is greyed out on this version even when set to expert mode. Any ideas? thanks y'all!
