Question / Help Screen flashes on stream

[mochahagotdi]

I'm trying to stream a windowed application using the Game Capture mode, but when doing so, the capture flickers.

Here is the log:

I would like to only stream the specific application, thus the reason for using Game Capture mode. Any ideas?

What game is it? Does it happen with just that game?

 

[mochahagotdi]

It's not a game, but rather a virtual radar client for the VATSIM network. More information can be found here: http://www1.metacraft.com/VRC/ According to the documentation, it requires a video card with OpenGL support, so my assumption is that the application (VRC) utilizes OpenGL to draw.

I tried running game capture mode on its counterpart application, vSTARS, and it works just fine without any screen blinking/flickering. http://vstars.metacraft.com/

Well that's a whole different sort of thing, game capture is sort of made for games I have to admit. I'm not entirely sure, if it doesn't run in fullscreen mode though there are other ways to capture it. For example, window capture with aero disabled, or monitor capture should be able to capture it I believe.
