--- Comment #4 from Alexander Stein <alexanders83 at web.de> ---
Apparently this is due a custom modesetting I needed to use before attaching a
AV receiver. My TV required a custom modesetting with resolution 1360x768, but
this is not supported by the AV receiver. So when using the unsupported
resolution with panel scaling nothing is displayed.
In my case I could remove the custom modesetting as the AV receiver has a
proper EDID with 1920x1080 (which is scaled down by that box for the TV). If
someone needs a custom modesetting the old fullscreen scaling should be used,
e.g. 
xrandr --output HDMI-1 --prop 'scaling mode' 'Full'
