I am having the same situation. From the task manager (I actually use Process Hacker) I can often see GlassWire using lots of not only RAM but CPU.
I wasn’t though sure it would be GW leaking into the non-paged pool, so I ran some generic google searches until I found a thread at superuser dot com (sorry, new user, cannot post links and only one image apparently) named “Windows 10 high memory usage (unknown reason)” which you can google
from which I learnt to install Windows WDK to have access to poolmon.exe,
with which I then identified that the biggest (and continuously growing) occupier of this non-paged pool, has the tag GWCD, which by the letters already gives a hint,
but I followed through with the instructions
until I ended up with gwdrv.sys

which when I right-clicked and went into properties,

is a digitally-signed (by Symantec) GlassWire Driver (as per the description) copyright SecureMix LLC which from what I’ve googled, is the maker of GlassWire.
So I guess this excludes the possibility that I’ve got a virus infecting this driver?
Since I started writing this, the leak seems to have grown by about 30 megabytes. I really don’t like to have to be rebooting all the time… I use lot of stuff at the same time and reopening my environment is annoying. I simply suspend the computer when I leave and like to reopen my session exactly as it was.
If not for this new issue, I never need to do it otherwise, always good performance and stability. But if I don’t reboot for a while, one day I get to the machine and it’s crawling crawling crawling… until it dies (this happened when I left it for some 48 hours without suspending).
By the way I’ve just today updated to the most recent version of GlassWire, problem continues. Apparently even with app updates, the driver is not updated since 2015, looking at the properties above.
Look forward to a solution, I really like GlassWire.
