[Gimp-user] small green rectangle in each image

[Carusoswi <forums gimpusers com>]

When I open an image (8-bit tiff converted by gimp from 16-bit), there is a
small green triangle in the upper left corner.  Happens with each image that I
open.

If I use another viewer to view the 16-bit image, it appears without this
rectangle.

What could be causing this?

I can clone out the rectangle, but something must be causing it.

Have uninstalled/re-installed several times with not change in this behavior.

Thanks for any advice.
