I would just like to say I have never had any problems with the webos 1.xx on my TV over the last year. I have simplink running, Chromecast, use WIDI, have laptop attached with HDMI with KODI for HTPC and 90% of my streaming, 2 TB disk attached for recording and Time Machine for live pause etc, digital out to home audio system, Android box attached via HDMI, DTV via UHF, use the 5 ghz wifi without issue. It could be a bit quicker booting up but other than that I am very happy with my LG.
Is it possible the problems people are experiencing are 'model' of TV related from the 2013/14 range.
