After upgrading to version 8.4x, there are abnormal performances, while the previous version 8.31.4 was normal

Unable to rotate to the front face.It will mutate when rotated halfway.

I’m taking a look.

problem is in loading a GS and then loading a new one. I’ll find a fix.

As a workaround, do not load the ply in the constructor and everything is fine:

I know this handling method, but I want to know why it is like this, because I have logic to update the ply data later, which will also cause this problem. The reason why the update logic was not reproduced in the playground is that gs.splatsData is null in the playground, but has a value elsewhere.
