When I play a 720p HD video and use the mirror driver begin to capture the screen,I got the screen tearing.It's more obvious when the image changes faster.The video play return to normal after I disable the mirror driver.It is normal if I don't play video.

The video is 1280x720,6000kbps,23frames/s.

The pc hardware is i3/4G/firepro w4100 GPU.

Anyone who can help me?

A mirror driver is a gdi driver without acceleration.
When active, the real videodriver disable acceleration is put himself in basic mode.

-try another player
-activate player after the mirror driver is active

firepro w4100 is a fast card but with a mirror driver it run in basic mode.
Thiscard is faster on WIN10 with desktop duplication as this use direct3D for screen capturing.
