Right side of the main window of QtC goes beyond the edge of the screen

I use a monitor with a resolution of 1600x1200. In debug mode, the right side of the main window of QtC goes beyond the edge of the screen.
Steps for running an application in debug mode:

• Pict.1: Before running the application. The main window of QtC is specially installed in not full screen:
• Pict.2: Debugging process. The right edge of QtC went beyond the screen:
• Pict.3: The debugging process is completed, but the right edge QtC is still outside the screen.

In full screen mode, the behavior is similar.
