WindowServer memory leak

Looks like this problem is coming back in High Sierra.

I have a late 2013 MacBook Pro Retina, freshly installed High Sierra after resetting SMC, PRAM, at most 6 apps open at the same time, after 16 hours, this WindowServer process is taking almost 1GB RAM! Notice how much has been compressed. Several days ago, I have been using the High Sierra GM for about a week without rebooting/logging out, and I noticed this WindowServer process took 8GB RAM!

MacBook Pro with Retina display, OS X El Capitan (10.11)

Recently I started to use Dell P2416D as external monitor, and also got stuck with the memory leak issue. Now WindowServer has used more than 6GB RAM. 😟

I hope you are sending feedback to Apple using the Feedback Assistant app.

It's been several days since the 10.13.2 Beta install without a reboot and the memory usage is currently 175MB whereas it would be into the GB by now previously. Submitting feedback report to Apple.
