I have drawing with added reference image. I just wanted to add some details, in which image was a little too disturbing (i was going to draw black line over black area in picture...) So as in previous versions i selected image, go to properties and want to lighten picture so i still see it, but it will not interfere with drawings. And... image does not react on changes to any of 'brightness', 'contrast' and 'fade'...

So return to 1.4 to finish my work... Or i missing something ?
