Persistent Data is now shared between F12 renders and viewport rendering (doubles up, leading to out of memory) #107370

Worked: (newest version of Blender that worked as expected)

Short description of error
I have a scene about 1.7GB in size with 4K textures but renders in 2K using simplify, blender crashes when I open the file > hit F12 and render the scene then close the render windows and switch to render view > it starts compiling then blender closes, in the past it would show out of memory this report:

#105522 (comment)

This issue happens only when persistent Data is active

unfortunately I can't share the file at the moment.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Could you recreate a file, not necessarily the one used, so we can replicate the problem?

It would also be interesting to identify what in the scene is causing the problem. 4K vs 2k texture, Geometry, GPU vs CPU...

Note that the triage team needs to confirm the issue before forwarding it to the developers. (Showing crash logs to developers directly is only a last resort)

Ill test with another files, I use GPU Cuda, simplify to 2K Textures and persistent data, the main issue I noticed is persistent data, will try to reproduce it in different file though

Poke. Any update?

Unconfirmed issues with no activity for more than a week are closed because, per tracker policy, we assume they are gone.

Still Crashes only when persistent data is On same as before, tested in Cuda

Need example file so resetting the status.

Hard to guess a possible culprit by looking at the call stack

The issue is that when activating the persistent data, when i hit F12 and render the scene, and the render finishes the VRam is still full, unlike when deactivating the persistent data, the Vram goes down the moment the render finishes, so obviously when the Vram remains full even after render finishes, Blender will crash when switching to render view cuz there are no memory left for it, all is full by previous render, the screen shot shows the vram after rendering the scene with persistent data ON and closing the render window and deleting everything in scene, the Vram is still full
I have an example file it's about 1.5 GB let me know where to upload it. Thank you

Here's the file: https://drive.google.com/file/d/1Jq6QY7RgEzk43uIQdPCRKsGAz0NVFQ5x/view?usp=sharing

Steps:
1.Click Render
2.After Render Finishes close render window then switch to render view
-Try both Cuda and Optix
