Problem:
Despite reinstalling everything I can think of I am having an issue with certain highlights tearing. This issue has been present for me in both GNOME and KDE.
It seems to appear consistently while using Firefox and KDE Plasma 5 desktop, however I have seen it happen in other applications (ex: Ubuntu Settings and Dolphin). It seems only to happen in certain programs: Slack, VS Code, Atom, Gimp, and Google Chrome, have never given me problems.
All the tears seem to be from highlighting something or hovering over a button. Maybe the commonality is something to do with performing a fill?
I'm not the most experienced with Linux so I am thankful for any help.
I believe this person is having the same issue

If you need any more info just ask. But please someone help me!
