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).

What target platforms are you seeing this bug on?

Linux

OS/Browser name and version | Device information

I tested on
OS: Fedora 43, Almalinux 10.1, CachyOS, Ubuntu 24.04/20.10

CPU: AMD Ryzen™ 7 7735HS / Intel i5 12450H
GPU: AMD Radeon™ 680M / intel graphics / Nvidia gtx 1650

Does the problem occur on emulator/simulator as well as on physical devices?

    We also observed a memory leak on Linux Desktop with Wayland on embedded ARM cpu and an OpenGL ES driver.
    Any animation causes an increase in memory. We are not sure if it's the same issue as the one reported above but is suspiciously similar.

    P.S. Running in software rendering mode (FLUTTER_LINUX_RENDERER=software) solves the memory leak.

    Thank you for your comment, but the error reported here does not seem to be related to animations, as it can be replicated with the counter example.
    Other things to add: impeller does not solve it, nor does switching from gtk to libhandy. The only way to solve it is by forcing the use of x11 or xwayland, or, as you mention, by forcing software rendering. This error even affects 3.41.2. The only version where it does not occur is 3.35.7, but it is a bit old. I would like to be able to edit the report to add the indicated tags, but I cannot find the options😅.

    Hi @Seom1177 , thanks for reporting.

    Since this is isolated to the Linux Wayland, I am routing this to the Linux team for investigation.
