Cinematics are lagging/glitching most of the time.

Summary

My cinematics are lagging/glitching most of the time.
In the video attached (on iOS, but the same exact behavior happens on Windows), a simple cinematic of moving two props lags and glitches. As you can see, if I trigger the second cinematic of “Closing,” it skips frames most of the time.
Strangely, if I wait a few seconds before triggering it, it completes without lag.

This happens in other cinematics in my maps. All are triggered by Verse.

Streaming is disabled. Nav mesh, “Can Affect Navigation,” and collisions are all disabled in all meshes inside the cinematics.

I saw other people complaining about this, but I didn’t find any solution. The posts are old, and nobody responded.
