Question / Help blender 2.78c flakey on 19.0.3 Windows 10

[fouts]

Is this behavior normal?

OBS appears configured properly: Display capture works and video device capture with a USB webcam works.

Blender window capture is always blank.
Blender game capture is flakey. The capture will go blank at random.

I can duplicate this behavior:

• add a game capture source
• set the mode to Capture a specific window
• set the window to [blender.exe]: Blender

blender window shows up fine. But it will go blank at random. To force the window to go blank

• click on the eye icon to hide the blender source
• click on the eye icon to reveal the source. It will now be blank

To restore the source, hover over the blender window and wait. It usually returns within a few seconds

You should probably be using display capture. Not all applications render in a way that can be easily captured in OBS.
