Why is KDE desktop so stuck?

My laptop CPU is AMD 8845H, and the graphics card is nvidia4060.Using the latest nvidia graphics drivers.Using the latest cachy os.

Every time I use the KDE desktop (Wayland), I feel that the KDE desktop is very laggy, and the desktop effect drops frames and stutters (e.g., magic lamp effect). Do you guys have this problem?
When I switched back to the GNOME desktop, thankfully, the system was finally silky smooth and smooth.

I would like to know why this is and how to fix it accordingly.
