moOde 5.0 RC1 In-Place Update

[Supersurfer]

I am using the default theme and a picture as background. Ios 12.0.1 and put the webpage as an app on the start screen.

Okay, I can repro this using your settings and a background image, although only in Landscape orientation, not in Portrait.

If you're comfortable with ssh you can edit the file in-situ by going to the moode instance

1) ssh pi@moode.local (password is 'moodeaudio' unless you've changed it)
2) sudo nano /var/www/css/panels.css
3) control-w (search function for nano) '.ss-backdrop' (without quotes)
4) change the line to this:

.ss-backdrop {min-width:100vw;min-height:100vh;max-width:unset;transform:translate(-50%, -50%);background-position:center center;position:relative;top:50vh;left:50vw;}

5) control-x to exit nano, press y to save the file and then return to accept the filename to save.
6) refresh moode

FWIW I made a really simple iOS app that creates a webview for moode, unlike the save to home page version it remains in memory when you switch out to another app which is a much nicer experience. I'm not sure we'll ever put it in the app store (since it's just a simple webview that runs the webui it likely wouldn't pass review) but we'll eventually put it on our GitHub and it'll be possible to compile & install it on individual devices with Xcode. Unfortunately unless you have a developer license you'll need to re-install it ever week or so as the self-signed certificates expire fairly quickly.

Thank you for your reply.
I tried this and it helps, sort of....
The white banding is gone but the background picture is stretched a lot. Can I scale this?
