Screen artefacts followed by sudden reboot - "video scheduler has detected a fatal violation"

Hello -

About 30 minutes ago I noticed some text artefacts while watching youtube videos that looked like this:

As you can see in the second screenshot, the artefacts disappeared when highlighting the text. The artefacts only appeared on my second monitor and disappeared when dragging the window back onto my main screen. It also only seemed to affect firefox (and possibly only specific fonts as it didn't happen on google or reddit except for italic text) and I couldn't see any artefacts in windows explorer. While taking the above screenshots my laptop rebooted automatically.
