Description
Preliminary Checks
- I have read and understood the important section above.
- I have searched existing issues and avoided creating duplicates.
- I am not filing an enhancement request.
- I have checked that this issue cannot be reproduced on Mozilla Firefox.
- I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.
What happened?
I'm not really sure this is the right place to report this, but I recently got a notification from my system about some part of Zen having being closed due to it malfunctioning.
My system
Operating System: Fedora Linux 43
KDE Plasma Version: 6.6.2
KDE Frameworks Version: 6.24.0
Qt Version: 6.10.2

Graphics Platform: Wayland
Processors: 4 × Intel® Core™ i5-2400 CPU @ 3.10GHz
Memory: 16 GiB of RAM (15.4 GiB usable)
Graphics Processor: Mesa Intel® HD Graphics 2000
Manufacturer: LENOVO
Product Name: 7052A9G
System Version: ThinkCentre M91p
Expected behavior
No component should come to be closed
Actual behavior
Some component came to be closed by the OS
Steps to reproduce
Sorry: no idea. I know that recently Zen became a little bit slower on my system, but I don't really know if this is related; I experienced some stuttering before getting the notification.
