I notice that you have an AMD Radeon HD 7750 / R7 250E. I'm getting the same thing in Ubuntu 14.04 "Trusty Tahr" on an AMD Radeon HD 7870, but it's not restricted to Firefox. I see it in other apps too, including the terminal. I've heard that it is fixed in more recent kernel/mesa combinations such as those used in Ubuntu 15.04 "Vivid Vervet" but I'm not able to test it at the moment? Are you?
