SUMMARY
I have a problem with kwin_wayland. Over time, it uses more and more memory until system starts swapping and becomes unresponsive. This is very noticeable when I do web coding. I use JetBrains IDE and Firefox browser. I have these apps opened for a longer period of time (today it's for 2 hours), and eventually I have to restart my laptop because it becomes sooo slow.

I have 32 GB of RAM, so that shouldn't be an issue. When I close all apps, kwin_wayland still sits on that memory and won't release it. I use built-in 4K screen with HDR + 2K external screen.

Is there any way I could obtain more insights into what's happening and to send it to you?

STEPS TO REPRODUCE
1. For me just use JetBrains IDE + Firefox for longer period of time.

OBSERVED RESULT
Computer slow down until it's unusable and must be rebooted.

EXPECTED RESULT
No slow-downs.
