Hello, my VPN is currently disabled. Should i try uninstalling it for now? I did try disabling all my plugins, which are: Adobe Flash Player (which was already disabled), AdobeAAMDetector (i think that's for photoshop updates), and Google Earth plugin. The problem still persists after disabling plugins. The past few times i've logged into my Mac a dialog box pops up and says something along the line of "AAM updater is not optimized for this Mac, it needs to be updated by the developer". Do you think that could be related to my issue? Is there anything else you think i should try? Thanks again for all your help!

I opened AAM to see if I could update the application, it updated automatically and closed. I tried to reopen to check the current version. Now it has a question mark over the app icon in my launchpad, and doesn't open. Either way it seems like i'm not having the problem anymore. I'll keep testing it the rest of the night but i tried around 10 videos, opened multiple tabs and tried then tried more. It seems like it's working now, I haven't had the issue once. I'll post again if anything changes, and once again, thank you.

So unfortunately I spoke too soon. It started happening again pretty much right after I posted my last reply. I did however figure out a work around. I changed my resolution from "default for display" to "scaled, 1280 x 720". While it's not the best resolution it does stop the distortion. I still wish I had a way to fix it completely, but for now it will have to do. Either way, thanks again for helping me out.

I downloaded chrome and and tried playing the same video, it definitely works fine in chrome. I did find that changing my resolution to 1280x720 did work for me as well.

I really don't know how to report it to Apple. I'm sure someone in the forums here knows how to do that. I was in the beta program and they give you a feedback app that collects data and reports the problem to the developers. I actually just checked and I still have the feedback assistant app. I'm going to try to send them the issue we're having. I'm not sure if it will work since I'm on a regular version of MacOS. I'll report back in a little while with what i find out.

Also I agree it seems like a problem with Safari. The weird thing is that this problem happened while I was on a beta release, and I got so fed up that I reinstalled a regular version. Everything was fine until a week ago with the last two updates. I searched the internet for months trying to find if someone else had the same problem. I feel a little better that it's not just me, I thought maybe I broke something.

Eric, thanks a lot for responding so quickly. I will try to get this info as soon as possible.
