Your image is truncated. Make a screenshot of the entire desktop so we can understand what exactely is the problem.

My screenshot was in fullscreen mode. Here is how it behaves when is in windowed mode.
After seeing your screenshot I believe it's related to monitor dpi.

And I noticed that I'm not being able to maximize the window size by clicking the square icon at the right top corner.
