Taking screenshots does not work on Scalismo 0.91

Taking a screenshot either from the GUI or from the program, results in an image in which the object shown in the window is moved to the upper right corner.

I observed once a similar behavior (Windows). Can you try to change the display setting in Windows to not scale things due to high DPI resolution? Default is 150% on my machine, setting it to 100% was the workaround back then.

Thanks for the suggestion. This seems to solve the problem. Unfortunately it is more a workaround than a solution.

A possible solution could be to use vtk directly for doing the screen capture:

First tries were, however, unsuccessful, as it causes the whole UI to hang indefinitely. My guess is that it is some kind of threading issue.
