@d683d6cc @ae9c8437 I just did a jam game in godot4 where there was a big spike the first time you place an object with a particle effect, and I think that was this bug too. It might just be web exports that are hit 

 @e83a408b oh yeah web is weird in 4 haha.

Iirc Juan said it will he fixed in 4.1 or 4.2 (will try it out when the beta is out or rc)

Anyway I‘m happy that I don’t have that problem anymore. 🙏
