Blacked Out Loupe View in Develop Module
It seems that since the update to "Classic" that at every start up of the program I can develop one photo and upon moving to the next loupe view is blacked out. In other words in the main view for developing the photo it is not visible. In reference and before/after views the photo is visible. Loupe view is however visible from my second screen. This makes it quite awkward to edit. See the screenshot below

My OS is Windows 7x64 and my Lightroom is version 7.0.1
