What do I do if I am experiencing noticeable cut lines or "tearing" of the screen image while using Circuit on Windows?

Last updated:

If you are using Circuit on a computer that is running Windows Vista or a later Windows operating system, you may experience noticeable cut lines or "tearing" of the screen image when you are switching between your Circuit client and other application window(s), or when moving or resizing an application window that you are sharing in Circuit. This is known as screen tearing.

Screen tearing is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. It occurs because screen drawing is not synchronized to the refresh rate of the display device.

To reduce or eliminate the problem, if your computer system meets the hardware and software requirements to run Windows Aero, set your display to use Windows Aero. Otherwise, set the display to PC Only or Extended.

If the problem persists, make sure that the display is configured to a refresh rate that is supported by all display devices.

Note: Switching to a Windows Aero theme reduces also the problem that other participants may experience when you are sharing your screen, where the shared content appears to blink.
