STEPS TO REPRODUCE 1. Use KDE Plasma as normal for a few hours, alt tab frequently, I used Audacity, and I closed it quite a lot while transferring sound files one at a time from my local storage to my media server using the split view. OBSERVED RESULT You'll see a delay of 1-2 seconds when switching tabs that won't go away no matter how many windows or processes you close. Everything else should perform as expected. EXPECTED RESULT Alt + Tab not slowing down at all after several hours. SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: 6.3.3 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.2 ADDITIONAL INFORMATION
Forgot to add, I'm using the 6.13.6-zen1-1-zen kernel (64-bit).

So I've done some using of my computer for a few hours, and it's definitely the combination of what I was doing with Audacity, Dolphin and transferring files. The alt tab is still fine even after sleep mode which was another theory of mine I had. Hopefully replicating it will show some possible results on your end?
