Hello, something strange happens to me with Mega Drive games, and it randomly leaves the full screen for a few moments, but this strange flickering happens to me even in windowed mode. I leave a video so you can watch it of the game Castlevania - The New Generation (Euro), although it happens to me with all the ones I have been trying.
My video configuration has not changed: Directx9, 4xBr, Force 60hz, Triple buffering and resolution 2560+1440, 32bits, it didn't happen before.
