A few of my cats over the years have had similar where it weeps constantly as the trapped fur pulls the scab open over and over as they move around and groom themselves until the underlying wound heals and the sticky, gooey mess of fur and scab come off.
Easy fix, start giving them a head rub then when they move their head to provide better access to the part they want rubbed or scritched use your other hand to slide the book out.
Thought about getting a AMD card but as I had only had one major issue with my previous 1070 (that was fixed by reloading my Timeshift snapshot then not upgrading the driver until the next version) so I thought that I would continue with Nvidia.
Eh, I can't change it for now but at least I know what is causing it and can work around it.
