I recently updated my Nvidia Driver to the latest one and after doing that there are now pixels randomly on my screen at certain times either different colour or just random.
It can do lines, small patches of pixels or big boxes of pixels covering the top to bottom of the discord chat box.
I have no clue how you can reproduce this I've restarted my shadow didn't work, I attempted to change my monitor settings didn't work, so I'm unsure what to do.
