Grid, Square and Track Galleries do not work well on Mac High Sierra

When using the Classic Gallery in the web module everything seems to work as it did before.   The Grid, Square and Track galleries will display the group of photos on the main page but when you click on a photo to display it then it sometimes works but generally the display corrupts and the only way to get out of it is to select a different Module like Library and then return the the Web module.  This sometimes doesn't work unless you select the Classic Gallery before doing the module switches.  For instance, this is what you see in the Track Gallery for the full photo.     Lr2015.12.
