I've got a problem with the windows on my desktop. If I want to enlarge it with the mouse by dragging the edges or corners, the enlarged portion is transparent until I let go of the mouse. Likewise, when I move the window around my desktop, the original window is still in the same place visible while I only see the edge of the moved part until I let go of the mouse again.
The problem may have occurred since I last updated my graphics driver version 15.12 Graphics Chipset AMD Radeon HD 7700 Series. Maybe it has changed anything in the settings but have not been able to find out what.
