ADDITIONAL INFORMATION
I am on Hyprland but also have Kde environment. The above 'Observed result' is on Hyprland but on Kde it's also same except that instead the beginning memory consumption starts up at 172 MB and after launching gui it stays above 200+ MB.

How are you measuring?
Have you accounted for mapped but shared data sections of libraries?
