I can't reproduce the rendering issue on the latest Nightly 50. 

Frank, can you please confirm whether this issue still occurs using Firefox in safe mode or with a new profile?

I have the same issue when starting in Safe Mode as well as when creating a new profile and start Nightly using this new profile.

Are you doing something in particular before having the rendering issue(like maximizing or minimizing)?

Could you please navigate to about:support click on the "Copy text to clipboard" and paste here the input?

No, I'm not doing something special.

I added the output from about:support as attachment

Frank, could you please tell me if you had these issues on the previous version of Nightly 49? Also, could you please confirm that these issues are reproducible on the latest Firefox release (version 47)?

Closing this as incomplete due to lack of additional information from the reporter.

Frank, please feel free to reopen it if you still have the problem reproducible (on the latest release) and you can provide additional details that could help us reproduce or identify your issue.

After deleting all profiles and recreating one, the issue seems to be gone
