Run `IOAccelMemory` in the terminal to see what's causing that (dirty and wired columns). It's probably an app with a lot of windows.
Or for general memory `footprint` is good.

Still does not explain why this balloons over time. Aka if I restart my Mac right now and reopen the same exactly apps with the same exactly windows the WindowServer will take 80% less memory.
If you send me the number it will get looked at.
