Description Hans Lambermont 2016-11-23 20:28:32 UTC 
kstars-bleeding 5:16.10+201611202010~ubuntu16.04.1

The histogram scale can be changed from its default 'Linear' setting to 'Logarithmic' and after clicking 'apply' the histogram gets updated. So far so good.
Changing back to 'Linear' and clicking 'apply' however does not work.

Furthermore setting it *again* to 'Logarithmic' and clicking 'apply' gives an even stranger result where the histogram moves right even further. This can be repeated a few times.
