No dark background possible; background slider dissapeard
OS- Ubuntu 18.04
In Shotwell 0.28.2 there was a slider in Shotwell preferences where I could adjust the background color from white to black (slider). See picture 1 1_-_Shotwell-0.28.2
In Shotwell 0.30.1-1 (ppa:yg-jensge/shotwell) this possibility disappeared. I cannot make the background darker. The background stays light grey. See picture 2
Is this a bug?!
