Hello, I installed Synfig today and I try to use it. But here seems to be a bug, because all is white.
I take a screenshot.
Moreover, examples are white too.
I hope you could help me, thanks 
Check out this: Menu>Edit>Preferences>Gamma
Be sure the three gamma sliders are set to 2.2

Hi,
I see you run under Windows 10, so you surely had the automatic upgrade.
Did you try to reinstall your graphic card drivers ?
Sometimes upgrades can break color profiles, color channels and hardware acceleration.
all of my drivers are up-to-date. But I have an old laptop ( ~6 years old) and maybe new updates aren’t availables.
I’m having the same problem, but I’m running Windows 7. I was thinking it might be a conflict with the GPU. I’m on an AMD build with an ATI GPU. What do you have?
Hi,
Black level in the Gamma setup should be 0 and not 100 percent. 
Greetz!
