Persistent black frames with still image files

[jamesh3949563]

This is a new one to me -- I imported image files into a project (JPEG) and some of the images had a PERSISTENT one-frame black image that wouldn't go away -- as in, I could trim the frame, and the remaining clip would STILL produce a black frame.
The black frames also display if I convert to video, and similarly act...randomly...
Yes, I also tried going back to the original image files, saving/exporting/converting, and same weird effect with those files too.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean install of the latest Studio Driver (NOT the Game Driver)

If that doesn't work, try creating a new project and import the old one into it.
