System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-10-03 23:31, hash: 272a38e0c2

Short description of error
Seems to happen with OptiX set in the System settings. Cuda is slower on my machine, but doesn't seem to crash.

Exact steps for others to reproduce the error
On a more powerful GPU it may not crash.

Open the file:
local_view_switch_crash.blend
Switch to rendered mode.
Go into local mode for selected object (press " / " button). Then go back to full view. Repeat couple times. If that doesn't crash Blender, try spamming the " / " button for 15 seconds.

Thanks for the report.
Did this problem happen in previous versions of Blender?

(I don't have an Nvidia GPU available to test, so if anyone else can confirm the issue I would appreciate it).

I have impression that newest builds are more stable. Blender will still crash after I spam / button for 10-15 seconds in the test scene I uploaded. I am working on an even heavier scene right now which does crash more consistently when switching the views.

Can't reproduce this.

Please check if this happens with latest builds. If issue persists, check if this happens when you run Blender with blender_factory_startup.cmd file

@iss
Since blender_factory_startup.cmd resets "Cycles Render Devices" to "None", I had to switch to "Optix". I go to local view first. Spamming "/" key will eventually crash Blender. Here's a video:

I am checking latest and 886196b888 with NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12 with no crash.

Can you upload file C:\Users\TwaMa\AppData\Local\Temp\local_view_switch_crash.crash.txt ?
This could be specific to your hardware too, check if latest drivers do resolve this.

@rjg Can you check if you can rerpoduce?

@iss Sorry, I currently don't have time to look into this. I'm very busy with my thesis until the start of February.

Edit: If I get the chance, I will take a look. I cannot make any promises though.

I'm unable to reproduce a crash in a release build with the steps from the video so far. Tested on Windows with driver version 496.76 on a GeForce GTX 1080 Ti and commit 6b5e1cfaca.

Geforce Experience shows me that I have latest (game ready) driver which is 496.76. This crash happens only in Optix mode. Doesn't happen with CUDA.

@MarcinTwarowski Yes. Perhaps reproducing the crash requires very specific timing for when the switch from/to local view happens in relation to the OptiX viewport rendering?

Marcin Twarowski commented

2021-11-26 14:13:28 +01:00

@rjg
Hard to tell. How heavy the scene is probably matters too and 1080 ti is more powerful than mine 1080.

Don't have any good idea to check here really. Perhaps if you can run Blender with -t 1 argument it may reveal thread race condition if no crash will happen, but doesn't seem like that would be the case.

I don't know if I did it correctly. I made a .bat file like this:

cd "C:\Users\TwaMa\Desktop\blender-3.0.0-candidate+v30.d2e608733507-windows.amd64-release"
blender_factory_startup.cmd -t 1

I meant only blender.exe -t 1. I don't think our .cmd files do pass args to Blender.

It took a lot longer with -t 1 but it eventually crashed.

Longer render time is expected. Don't have other ideas to check really. Maybe if you try to simplify file removing half of elements at a time, you could isolate issue to particular object. But that wouldn't probably help with me reproducing the bug...

Marcin Twarowski commented

2021-11-30 13:44:53 +01:00

If I remove objects crash doesn't happen. I already tried to make the scene as minimal a possible, but it needs to be heavy enough to crash. It seems to have improved since I reported it anyway, it's not a big deal.

Now I have some evidence that viewport overlays have something to do with the crash. In the video below I was spamming "/" button for a minute but it crashed only after I turned on the overlays.

Cannot repro in eb3ff1d6f9 (possibly due to #94479}
Cannot repro in 3.0.1 release candidate 9600f36cfc either.

In both cases, I had to reduce the geometry though (only have a 6GB 970m).

@MarcinTwarowski : can you check if this is still an issue in these fresh builds from https://builder.blender.org/download/daily/?
If so, I have added the Unconfirmed tag with the following consequences:

The issue reported can't be reproduced so far, and has been moved to the BF Blender: Unconfirmed project.
If 2 other people aren't able to redo the bug after 2 weeks, it will be closed.

We appreciate the effort that goes into making bug reports, but to be able to fix bugs we have to be able to redo them.
If there is anything you can provide to help others to reproduce the problem, be sure to include it.

Hm, so there is something in 3.1 that would be nice to have in 3.0.1 as well [though not entirely necessary].

@Sergey, @pmoursnv , @brecht: any ideas which commit could have fixed that?
If not, we just go with 3.1 and leave 3.0.1 as it is...

Sorry for the confusion, but after almost 2 minutes of spamming the / button I was able to crash Blender in 3.1 too.

When I first reported this bug crash happened after couple clicks, now I have to spam the button for a minute or two. Probably not worth investigating, especially since others can't reproduce.
Something new happened while I was smashing the / button:

Materials didn't render on some of the objects. Again, not sure if worth investigating.

Since we seem to get stuck here (and this has been unconfirmed for quite a while now), will stick with the tracker policy and close.
(of course feel free to comment again if this can indeed be reproduced by someone else, we can always reopen in such case)
