High CPU usage from kwin_wayland after Plasma 6.7 upgrade

Hi all,

After upgrading to Plasma 6.7 I'm finding the kwin_wayland takes some 8%CPU when idle with nothing open. When I have firefox open on some sites it spikes up to 50% even though there are no animations (except a blinking cursor, like the arch forums). I tried setting my environment variables to force wayland (MOZ_ENABLE_WAYLAND=1, QT_QPA_PLATFORM=wayland), and I played around with my i915 module parameters (enable_psr=0, enable_fbc=0). But no luck. Any idea what the problem might be and how I can fix it?

If it helps, here's my sytem info:

Operating System: Arch Linux
KDE Plasma Version: 6.7.0
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.1
Kernel Version: 6.18.36-1-lts (64-bit)
Graphics Platform: Wayland
Processors: 6 × Intel® Core™ i5-9600K CPU @ 3.70GHz
Memory: 16 GiB of RAM (15.3 GiB usable)
Graphics Processor: Mesa Intel® UHD Graphics 630

Thanks in advance,

GI

qdbus6 org.kde.KWin /KWin supportInformation
glxinfo -B

Does intel_gpu_top suggest the IGP is being utilized?
