V0.13 is the first release based on Qt5, which brought several technical changes. The most critical is that rendering graphics with Qt5 requires at least OpenGL2.1 support. This normally utilizes a dedicated piece of hardware, the Graphics Processing Unit (GPU). Any recent (say, post-2011) hardware should provide sufficient functionality, but you may need to update the driver not just with the built-in Update driver search of your operating system, but with drivers downloadable from the graphic card manufacturer's website. (Sometime drivers for notebooks can only be found at the respective notebook manufacturer's support websites, and using the reference drivers from GPU manufacturers may not be completely compatible.)
