Does that also happen if you disable hardware acceleration?

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Maybe, maybe not. Like it says on the tin: "Aurora is not for the faint hearted".

Do your bit and report the problem to Mozilla, link in the Help menu.

Super detective work! I turned off hardware acceleration and no more diagonal lines. As far as I know, I am using the latest Nvidia drivers and software. I can live with the lines, so I will turn on the hardware acceleration again.

Thanks, Fred
