I'm using Firefox 26.0 on Windows 7 64 bit on two computers. One computer is displaying this: http://imgur.com/G2PfOWJ And the other is displaying this: http://imgur.com/cMSX8mn As you can see, the first one had a seamless top portion while the second one has a rather unsightly cutoff. The first image was taken from a 1280x800 resolution while the second was taken from 1920x1080 resolution, if that matters at all. I am submitting this from the second computer, so the troubleshooting information is coming from the computer displaying the second image. Would appreciate any advice, thanks.
