Camera window flickers

I just started using harmony 15. And Every time I move around, or edit the model in the camera window, The background (grey) , goes to dark grey. If I go into a drawing, it goes to dark grey and stays there while I draw… which makes sense, letting your know your in a drawing.

But while Im editing the rig and moving it around, the screen constantly flickering to dark grey when I click on something, and then back to light grey when I stop clicking, is getting very annoying. I usually animate pretty fast, so its like a strobing effect… getting hard to look at.

Does anyone know why it’s doing this, or what this is?

thanks.

That’s not normal, try re-installing your graphic card driver.
Close unnecessary programs and web pages while animating.

Contact support to have a look on your computer if that doesn’t
resolve the problem.

Uninstalled and re-installed the driver like you suggested. The problem went away. Thanks!

Actually. I just noticed it was the colour card flickering not the screen. I disabled the colour card, that’s why its not doing it anymore.
Just thought I’d post this, just in case someone else is having the same issue.
