I don't want anything. I wanted you to check if you had any, that might be effecting how the page was loading.

Does the page behave differently with adblock turned off?

you did, by looking in your extensions.

If shutting off extensions doesn't change the behavior, then I'm going to blame the website for having a bug.

It could be a safari bug. Each browser has them. At this point, I'd use chrome!

Your symptoms and analysis point to your MBP. Since no other app shows the glitch, it also has to be responsive to software, which rules out the display, cable, and connectors. That pretty much leaves the GPU or CPU (embedded graphics), those are where software stops.

Safari may push the graphics functions a little more than 3rd party browsers. Apple trying to optimize more, and taking advantage of writing the graphics drivers. If a small GPU glitch appears only under load with certain graphical API calls -- You could try running something graphically-intensive in another window (a game perhaps, in windowed mode, and with sound turned off) to heat up your GPU. Work as usual, and see if Safari will show the glitch more frequently.

Of course, catching it wouldn't help. If the above analysis is correct, the only solution is a motherboard swap or another MBP.
