I would chalk it up to Windows 10 and compatibility issues with AMD video cards. Is AMD still refusing to provide drivers for Windows 10? If so you could very well be running on an inferior driver written by Microsoft. Open control panel and find device manager. Right click on the video card and select properties. Click the driver tab. Who is listed as the driver provider? Also, run dxdiag and see what version of DirectX you're using.
Edit: Well there's your answer. Looks like your Radeon R4 card may not be supported by AMD drivers in Windows 10.
AMD Radeon? HD 5000 and AMD Radeon? HD 6000 Series products should fully work in Windows
