Downgrading is difficult because of the APFS conversion. Sierra "supports" APFS, but another version which is not compatible. There's no way around erasing the drive really.

Not setting a scaled resolution helped with the memory leak but I'm getting window server crashes now. Really regretting the upgrade.

I am running a mid-2010 mAcBook pro - and on High Sierra 10.13.2 I had bot windows server and Activity monitor running at around 35% CPU each.
I found a fix from here that worked for me - https://apple.stackexchange.com/questions/153397/windowserver-high-cpu-on-yosemite

I applied the first suggestion for the Mission Control. I did not have to log off for this to take effect.
  • Mission Control: switch "Displays have separate Spaces off", switch Dashboard off.Dashboard as an overlay really slowed things down for me
  • Fix disk permissions, reset System Management Controller, reset PRAM (Luis Mercado explained this well at https://discussions.apple.com/thread/6623697). I had some minor success with this, but the issue started occuring later anyway
  • Reduce transparency effects (it's in System Preferences > Accessibility under Display). I've tried this, it might improve the performance but I was missing the look so I've switched it back.
  • Switch off automatic graphic switching (System Preferences > Energy Saver). This was the best option for me, as I don't really worry about energy consumption, but honestly I don't think that there should be a real need for this.

I hope this helps someone else

I have it too. windowserver using 9gb of ram causing slow system. I have High sierra 10.13.3 suplemental update, I mean the last. I tried the default in display, dashboard off etc and the problem persist.

Edit: Unistalling nvidia web driver solve the problem. windowserver is always under 100 mb, Reinstalled nvidia web driver and memory leak is back. I will try an older driver.

Thanks for the update, Fernan0; I was almost at the point of installing the suplemental update when I saw the notification from your reply. I'll do a backup having this version (without the suplemental update), apply the update and check what's going on with the WindowServer process; gonna get back with the results.
If I may ask, how do you remove the nvidia driver? Do I need to install the nvidia driver manager, or is there a way that I can do that using the shell? Thanks.
