This is very likely related to video hardware, in particular the use of onboard "Intel HD" video hardware. First, if you have discrete video hardware (for example a high end "Quadro" graphics card), ensure that the control panel settings are set to use the discrete graphics hardware as the "preferred". Also, download and install the latest video card driver from the manufacturer's website. See: Updating video drivers and troubleshooting video hardware issues
