Whole screen suddenly becomes offset?

While switching between desktops to read tutorials, I noticed that my blender screen became offset. I cannot figure how to get it back to normal. The last time it happened I had to exit and restart. See attachment.

EDIT: I found that by moving the blender window to another desktop, fixed the problem. I wonder is it KDE related? I’d be interested to know if anyone else has had this problem.


were you alt-clicking and dragging, if so then that moves the window rather then in windows allowing the current view to be rotated.
