Flashing White Box at Bottom of Screen?

I've been having a problem where at the bottom of the map display there is a rapidly flashing white box that only shows up when tokens or the camera is moved. It doesn't keep me from doing anything, it's just really annoying.   ^^^ that white bar at the bottom I've updated my browser, reset it, and logged into my account from a different google account so I know that it's not an issue with my browser. I'm fairly sure it may be a graphical issue, because testing it on my sibling's computer, it worked just fine. (I've also went through all the steps listed on roll20 for fixing errors) This happens at any size map, no matter how small it is. Also I've never seen this error happen on any other website i've been on, so that's why I'm here. Has anyone else come across this error? If not does anyone have recommendations on what to do?

So if you've gone through all our steps for troubleshooting, at this point we just need a pair of console logs from you, one from your misbehaving session and one from your sibling's computer, and it would be helpful if you did the precise same things for each test session so our devs can look at the logs and see what happens on your system versus what happens on the behaving system.  Please make sure the logs start at your login to the table and extend through you doing a few things to make the box flash, and then the same activities on the other (non-flashing) system.  If you need help with getting the console logs, please refer to our Troubleshooting Guide .   Once you have posted the logs, a dev will be by to look at them.  In the meantime, on your flashing system, if you make a blank campaign and enter it does this problem happen there as well?
