Laggy timeline while 10bit footage stay in Source window (23.04)

I've noticed that when I grab a 10bit 4:2:2 footage to my source window and play the timeline have so much dropped frames, when I change the source to effect window the playback rolls with no frame dropping.

This not happen when I have a 8bit footage 4:0:0 at the source window

What is that media, and created by what?

Especially if it's Sony or drones, the AVC (Sony) or mp4 (drones) is long-GOP which is Hades to edit with, and requires special hardware bits. That's why I'm asking.

GH5 4:3 10bit 422 200Mbps LongGOP, the problems happen only when I have these files opened in source window. If I change to effects or any other window the timeline runs smoothly.

Thi wasn't happening in the last version, I've noticed because is what I usually do working with B-Rolls in my workflow
