Anyone have problem with Playback quality in 2.93.5? (low quality when playback)

I just updated Blender from 2.93.3 to 2.93.5 and everything working fine until I try playback my scene.

Viewport suddenly reduce quality! specially in shadow (in Eevee mode). normally the quality will look same as when stop playback. I try uninstall and install 2.93.3 again and problem went away. I’m not sure which cause this issue. Maybe new light system? Anyone else have this issue or have any solution. Please help.

I uploaded the simple video captured my screen when I try to reproduce my problem at URL below

Thank you in advance.
