Since I'm studying for exams I don't have much time for other things but I took a few minutes to check Gaul and Libby gifs, and found out that Council, MRG, Ageira, LH and HF logo gifs still have the jump at the end of the gif breaking the perfect loop, while I have no idea what exactly happened to the LSF logo, but certainly something horrible from the looks of it.
Will continue to check the rest once I've more time. Now back to mass spectrometry.
