I get this weird artifacting (look at link) when watching some videos in original quality. I have tried other browsers and computers and it is the same. If i change to quality convert it is good.

That looks like your video may have some spikes in the bitrate and the video player is getting overloaded at those points, which would cause the strange color bands. When you convert, PMS smooths out those spikes.

Looks like you were using Plex Web. You can try another browser to see if it’s browser related. You could also try using Plex Media Player in desktop mode, which is the same as Plex Web, but it will use the player engine from PMP which is much better than a regular web browser.

ok thanks Plex Media Player in desktop mode works great.
