Installed the latest update. Now if I change a folder view from list to icon view, for example, when I go back to list view the Finder window now shows up as a complete dark gray with no files visible at all. If I click in the sidebar to another folder and then return to the original folder the window shows up as normal, that is, white background and a list of files. Have never seen this behavior before.
Note, this only happens (so far) with folders on external devices or shared on a network. And it does not happen reliably, that is, this behavior shows up most but not all of the time, making it hard to figure out what is triggering it.
