[Linux] High VRAM usage when resizing desktop app on Wayland #182192
Description
Steps to reproduce
Create a new project, use Flutter 3.38 or later (also available in master), you need to launch the application with Wayland, change the window size multiple times (you can see this with resources, mission, or KDE monitor by enabling the video memory option), this only happens if the app is launched with Wayland, xon xwayland/x11 works fine.
On Gnome

On KDE wayland with x11 workarround

I am currently using 3.35.7 as it is the latest stable version without the memory leak.
Code sample
Use default flutter counter app or any project with latest flutter like snap-store on Ubuntu 25.04 (snap-store works fine on 24.04, but if you update to edge channel the error appears).
