Somehow after I updated to Windows 10, most of the OpenGL shaders are fuzzy or show a black screen. The only working are simple scaler and scanline. Is it a problem on my PC or Win10? How can I get to work? Selecting Normal Blits I can get HQ2X/3X but the screen is not full, it's a little square at the center. Can it be possible to strech to fill the screen an maintain 4:3? I don't know if it's a bug, but even when using win8 + fullscreen in OpenGL, when I pressed ESC the menu just wouldn't show up, like the screen freezes.
