Hi, I seem to be having this or a similar bug.

Operating System: Fedora Linux 41
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
Kernel Version: 6.11.11-300.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 6800H with Radeon Graphics
Memory: 30.5 GiB of RAM
Graphics Processor: AMD Radeon 680M
Manufacturer: LENOVO
Product Name: 82RG
System Version: Legion 5 Pro 16ARH7H

The laptop also has a DGPU: NVIDIA GeForce RTX 3060 Laptop GPU

NVIDIA drivers: 565.77

The issue seems to present itself when plugging in a monitor into the DGPU
while kwin is running. If the monitor is already plugged in while kwin is
starting (either at system boot or by running kwin_wayland --replace), the
issue is not present.

A work around I have been using is unplugging the monitor, at which point the
memory is still used, and then plugging the monitor back in, at that point the
leaked memory is cleared up, and the memory use starts slowly building again.

As you asked the others if using Nouveau stops the leak, I had tried to switch
to Nouveau, which did indeed stop the memory leak. However that had issues of
its own, one of which was Xwayland seeming to crash as well as firefox (which
is runnning on wayland). And then kwin spamming this in the logs: kwin_xwl:
Failed to create pipe to start Xwayland: Too many open files

Using the NVIDIA drivers with the memory leak is preferrable with the work
around.

As far as I know this issue started after updating to NVIDIA 565.77

Please let me know if there is anything else I can do to help debug this issue.
