Every time I scroll up or down in a relatively fast manner, the center of my screen has a line tear. I have tried disabling use hardware acceleration when available, but it didn't fix the problem. I have also made sure my Firefox is up to date, and cleared my cookies and Cache with CCleaner. I also tried using other web browsers to see if this problem on them as well. I used several other web browsers including Google Chrome and Microsoft Edge, and none of them had this problem. This problem seems to be exclusive to using the Firefox web browser.
