Another bug report: black bar on side of preview

See attachment 1. When I have my Firefox (current) window maximized at 1920x1080 and enter Preview, the rectangle from top to bottom of the tab, which includes the Edit/Preview toggle control, goes black. If I restore the window, this doesn't happen, only when maximized. If I switch tabs, then switch back, the black vertical bar disappears and the preview fills the window as expected. If I restore the window, go to Preview, then maximize it, I get both horizontal and vertical black bars. (See attachment 2.) Again, switching tabs and switching back restores normal function.

Firefox bug? Some driver issue? In any case, it isn't a dealbreaking bug, just something I thought I'd mention.
