redraw issue

When I am in three-pane view, I have an issue with the previous item being shown behind the current item. Known issue, specific to my system?

The screen grab show is the previous item, I’d describe it as a “background” to the current document selected. It’s like it’s cached in the preview window of the “as Three Panes”, lower window, right hand side. Document list is on the top right side and folder (group) list is on the left side of the view. In the screen capture below, the check is the currently selected document.
