XFWM4 eating up RAM (potential memory leak?)

Hi all!

First of all I want to mention that I have been stalking the net (especially this forum) for a few weeks now and I have not seen anything mentioned about this.
I am curious if anybody noticed this behavior regarding xfwm4 (latest)?
After a  few days of running, the xfwm4 process gets to eat (use) over 60-70% of available ram?  Available ram meaning 16GB.
This all started after a (very late) upgrade in ~December, if I recall correctly. I think it was the transition to the latest major change of XFCE4  (maybe 4.20).
I am a bit tired of killing xfwm4 every couple of days, then swapoff, swapon (to move back to ram the gigs of swap created) and pacman -Syu to see if some new update package fixes this.
I am asking in the hope that this is a behavior local to me and it is not worth the time to start digging with valgrind.
But if other people have noticed this, it might be time to do it.

Thanks in advance and let's hope I am right and wrong at the same time.
Also thanks to everyone for being a great community.

Not much detail in this post. Have a look at this upstream bug report. Perhaps its related.

Sorry that the post did not contain any more info. I just wanted to get a feel for the situation since I did not find the posts you linked.
Thank you very very much for that link. I think it "solves" my problem.
nVIDIA strikes again. I currently have exactly the same version of drivers as suspected there (565.77).
I guess AI first steals our (linux) RAM , then maybe later our jobs.

Let's hope the next version of nVIDIA drivers plays better with xfwm4.
