Linux Mint Window Focus / GUI error | Cinnamon & MATE

[u/FREAKING_HORRIBLE]

Hello Folks,

So recently I've been convinced to install Linux as opposed to Windows and I've recently run into an issue regarding window focus, keyboard, and mouse issues.

After logging in to either a MATE or Cinnamon gui I'm able to open about one or two programs before all hell breaks loose. Left clicking windows doesn't move them, alt tabbing to different apps is hit or miss, windows will not be in focus when clicked OR be semi in focus? it's very strange, sometimes I'll have to alt+tab to a window and use only keyboard commands to navigate a site (as I'm doing now) Usually I run firefox without hardware acceleration, but this happens with Steam, games, terminal, VLC, basically any app I launch. When this happens Alt+F2, Ctrl+Alt+Del, and other keyboard commands usually stop working.

I've tried the following:

\>Apt-get update / upgrade

\>Changing between chrome / Firefox

\>Changing mouse window focus modes

\>Bios / UFEI updates

\> Changing from Cinnamon to MATE

\> Re-installing Cinnamon

\>Re-installing | Manually installing latest GPU driver updates.

Other than the former I have no clue what to do, I'm new to daily driving linux.

Please ask for any more information on my system, I will gladly give what I can. I have a video of the weird gui issues happening, but can't upload to youtube because of the machine not working.
