If you get it working without cropping I would love to know what i need to do to fix it. Thanks again.

as temporary solution you can use the old Webplayer like me. I stored the bundle for you there:
Edit (updated Link): Cloud

1.
Download and extract it (ca. 10 MByte). Then search the Path of the installed Version, for me:
/usr/lib/plexmediaserver/Resources/Plug-ins-995f1dead/WebClient.bundle
The Versions-Tag of PMS changed with every Update, here 995f1dead (it’s hexcode).

2.
Replace the exisiting directory WebClient.bundle with the downloaded one.
Don’t forget to make a backup from the existing WebClient.bundle.

3.
Restart PMS and test the Webplayer in new Browsertab. Menu Preferences should show the version 2.0.7. (show pic).

This version also allows Direct-Play, the newer version always do transcoding. Unfortunately the compatibility with coming PMS-Versions cannot be foreseen. It works for me since February (https://forums.plex.tv/discussion/260454/no-directplay-with-httplivestreamurl-in-the-latest-web-players)

This allows to change between old and new plugin-functions.
