I've seen this happening before. Open your workspace in a text editor and
look what you have in tag display, attribute dim. You might have some
exceptionally large values there. This seems to appear only on Windows when
you save your workspace while the map window is minimized. You can edit
this value and put some normal value in there (like 300), save it and try
to reload it again.
