System Information
Operating system: Windows-10-10.0.22000-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1650 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.39

Blender Version
Broken: version: 3.0.0 Beta, branch: master, commit date: 2021-10-27 22:07, hash: b838eaf2b9
Worked: (newest version of Blender that worked as expected)

Short description of error
when I render with persistent data enabled and disabled I get different results when it's disabled it doesn't look right
more specifically just for the geometry nodes it's like using old data from a previous frame for some character in the text
well I got that idea from when the frame starts there are frames that the same character get above each other the other is smaller than the above one
so it's clear that it's taking data from frames that are maybe 25 frames before this problem magically disappear when I render all these false frames persistent data disabled
I'm not that sure
BTW for this specific file when I launch the render it just crashes I have the two files that got created when blender crashes here they are
11 cube for saying the dimension is a unit of length.crash1.txt

11 cube for saying the dimension is a unit of length.crash.txt

Exact steps for others to reproduce the error
the only thing you have to do to reproduce that error is to enable disable persistent data
I tried simplifying the scene but it looks like when I delete objects persistent data reset or something
I'll send the whole file
I'm really sorry for that
this is the file persistent data bug.blend

and these are some pictures:
what I get:
what I want:

thanks! have a nice day

This file appears to have many issues when rendering or playing back the animation. With the system described at the end of this comment I experience these issues:

On the second frame of rendering with Persistent Data enabled the main object shading is distorted:

Persistent Data off (expected result) Persistent Data on
When rendering I frequently face freezes, with Persistent Data on or off. For example, the animation will stop rendering at frame 60 and Blender just freezes. Or in another case, the Blender UI will freeze on frame 6, but the animation continues to render up to frame 58 and then freezes.
When playing back the animation in the viewport Blender will freeze.

Testing with Blender 3.0 the same issues appear. And these issues appear to be mostly tied to the "text" object.

As for the original reported bug with parts of the text disappearing when re-rendering the scene with persistent data on. I can confirm this.

thanks for the information well I'm still new to this website is there a way or a guide to know what should I do to help as a normal user

all of this happened but the persistent data never messed with shaders at least in blender 3.0

I don't really understand why, but I saw this fix used elsewhere, and it seems to fix at least one of the issues (deadlock in animation playback in the viewport (even without Cycles))

I was not able to reproduce the deadlock myself. It's possible that the bug is in BezierSpline::evaluated_positions. It locks a mutex and then starts threading while the mutex is locked. This is a recipe for a deadlock without task-isolation as mentioned in the comment about BLI_task_isolate.
