My screens (on two laptops and one desktop) are 1366*768, 1920*1200 and 1920*1080 and I have uptimes of a couple of weeks/months with no extra slowdown.
For me the problem is more noticable on Wayland (mouse/animations stutter) but it is also noticable on X (animations stutter, popup menus slow down videoplayback).
In my situation it has nothing to do suspend/resume and/or long uptimes, the issues are always there.
