Kwin efects with any transparent function doesn't play a role in plasma 6.6

My device:

OS: Arch Linux

Kernel: x86_64 Linux 6.18.9-arch1-2

DE: KDE 6.6

WM: KWin Wayland

CPU: Intel Core i9-14900HX

GPU: NVIDIA GeForce RTX 5060 Laptop

In my device, the kwin effects with any transparent function such as fading popup and fade in/out animation doesn’t play a role. If I try to use them, it seem like a window frozen here without any transparency change, and when timer goes, the window just disappear. The issue also exists in popup(overlay with each other)

So could I fix it? The gif just in fading popup effects and the popup just appear suddenly and disappear suddenly without Transition. I think it isn’t normal, and before I upgrade, it didn’t render like such problems.
