Disabling that extension seems to have fixed the leak. From the start I had appindicator also disabled, would you like me to enable it to see if this set up causes appindicator to spam the log every few seconds as well? I'll attach the log from gnome-shell to show the difference.

This memory leak does not happen if signal is being sent through the hdmi switcher either from the desktop itself or from some other device. It also does not happen if I properly turn the monitor off.
