This is clearly a leak in the gnome-shell process. Comparing the memory
consumption before and after shows a massive increase. Whether this
originates in mutter/mesa/wayland will have to be determined.
It can be reproduced easily while concurrently resizing any tiled
application windows.

Title:
Huge memory leak when tiling LibreOffice windows in Ubuntu 22.04
Status in Mutter:
Unknown
Status in gnome-shell package in Ubuntu:
Incomplete
Status in gnome-shell source package in Jammy:
Confirmed
Bug description:
Please do the following to reproduce the memory leak I can observe on
my laptop (Acer Aspire 5, Ryzen 7 5700U, AMD iGPU, Ubuntu 22.04 with
Gnome Shell):
Close all programs.
Open LibreOffice Calc and tile the window maximised on the LEFT side
of the screen.
Open a new instance of LibreOffice Calc and tile the window maximised
on the RIGHT side of the screen.
Now your screen is full with 2 tiled windows of LibreOffice Calc.
In the middle of the screen, drag now with the mouse the edge between
the tiled windows and move it several times randomly to the right and
to the left so that the size of both windows changes simultaneously.
Look at the RAM consumption in the system monitor!!!
On my machine, with numerous moves of the edge between the tiled
windows, I can make my 24GB completely full. Reboot empties the RAM.
Can you reproduce it? Is it only related to LibreOffice?
My system:
Ubuntu 22.04 with Gnome Shell
LibreOffice from the official repositories
Version: 7.3.6.2 / LibreOffice Community
Build ID: 30(Build:2)
CPU threads: 16; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: de-DE (de_DE.UTF-8); UI: de-DE
Ubuntu package version: 1:7.3.6-0ubuntu0.22.04.2
