The issue has reoccurred after the BIOS Update. Circumstances were similar, two logins, switching between them. The only other things occurring at the time was plugging in a USB Stick, and using the screen app (screen -R -D, to check on minecraft servers that were running). I believe I was logged into the 2nd account, but the USB stick auto-mounted under the first account (the one I had logged into first). Still no direct way to reproduce.
