Short description of error

I opened Blender and used it maximized (I pressed the rectangle in the upper right corner), after a while I minimized Blender and switched to my Desktop. After I clicked the blender icon in my taskbar the application didn't focus and after pressing the blender icon again I got a Blender window with an incorrect UI. The application did not respond and had to be restarted.

I disabled the OpenCL support for Cycles, because I thought it could be the reason but that did not help. I also uninstalled Blender and reinstalled it, but the bug still exists.

Exact steps for others to reproduce the error

Maximize Window
Use for a while (I rendered the scene with the cycles engine)
Minimize window
Click on the Desktop or another application
Click on the blender icon in the Windows Taskbar

Low Poly House.blend

Is there an easy entry point for beginners to investigate the bug? If so I would like to help resolve the bug myself.
