Q Light Controller+

i am testing and configuring a RPi 2 and the Rapberry 7" touch screen, when switching to smiple desk it scales outside the screen. the only way i found to get it back fitting the screen is a reboot, is this a bug?

after boot clicking simple desk after clicking simple desk

This topic has been discussed in the forum quite a few times.
If you are using the Raspberry Pi touchscreen, it would have been nice if you mentioned it...

You need to reduce the number of faders in the Simple Desk page, documentation here (see 4.1): http://www.qlcplus.org/docs/parameterstuning.html

This is the relevant post specific to the Pi:

You probably need to reduce the playback faders as well ('playbacksperpage')
