In the past few days, Blender has become unexpectedly unstable to the point that, while in viewport shading mode (using Cycles) if I selected an object in the scene it would simply close with no warning whatsoever.
I thought to start from scratch and so I deleted the config and I added one add-on at a time. I decided to reduce the add-ons installed (by a lot) and so far it seems the good stability I was used to is back.
If my test proves to not be a coincidence, I then wonder if it’s possible that having some add-ons installed may cause instability even when they’re not actively being used.
On a side note, something I never figured out: sometimes after a new installation or after cleaning the config file, the “Save This Image” via F3 in the compositor not always show up and the only choice is to use the button in the node panel. Weird.
In theory regular add-ons should not cause instability given they are only executed when they are called/fired by the user. However there are some special cases like UI additions, or custom function implementations in other languages that interface with the Blender API.
I actually have that issue too, Blender suddenly disappears when I click on an object or undo sometimes. Once in a while it happens when I change from shaded to wire view mode. I got a traceback and it showed some Nvidia driver crash which is generally not fixed by the devs given it could be a driver issue.
I had the feeling this could be due to some add-on, good to know this can very be the case.
All in all, starting with a clean configuration and going with fewer add-ons is a good thing.
I realized more often than not I end up installing an add-on as it seems interesting and then I forget about it and I never use it again.
I know that C4D sometime have “issues” because of plugins - scripts. Sometime program even won’t start or crash on start / exit. Sometime plugin interfere with C4D, sometime there is conflict between plugins. I guess that is same with Blender, especially because new version release almost on daily basis. Also if you are on win be aware that every PC have his own “personality”… I learn this old truth in hard way.
So, it didn’t last long, Blender is crashing again.
It seems it’s related to the GPU and it doesn’t make much sense.
This is the scenario: I’ve been using 2.91.2 since its release.
I didn’t update the video driver, the same Nvidia 456.38 whql driver which worked fine (and still does with the rest of my software).
The only thing I can think of is the latest Windows update. Hard to tell what could have caused such instability though, especially because it only happens with Blender.
Updating the video driver doesn’t feel very appealing considering that other than Blender the system is stable.
That is the error I got and I filed a Blender bug for it however these types of crashes tend to not grab developer’s attention since they are quite vague crashes.
Did you get to the bottom of it? I’m seeing the same issue with the same NVIDIA driver across a bunch of different applications ( though I’m , like you , getting the error only in Blender )
When I look at >> AppData\Local\Temp for the crash log the output is
Stack trace:
nvoglv64.dll :0x00007FFE94719470 DrvPresentBuffers
nvoglv64.dll :0x00007FFE945EE828 Symbols not available
I naively thought it might be that I was using mathematical symbols in the text fields that might have caused it, and removed those haha . No dice.
If there are any blender devs reading, there’s a guy posting on the NVIDIA site that seems to have found the specific draw call that triggers the crash:
@JohnnySix
Unfortunately, not. I also submitted the bug but it seems it’s hard to troubleshoot these sorts of issues.
I then tried 2.92 and the problem was gone, except now there are two new problems: in my case, one is BSOD, and more generically the other is performance degradation.
Too bad, I guess for now I won’t be using Blender much.
@JohnnySix@hubmer3 Would you mind sharing the installed add-ons on your machine?
I thought if we take a look at what we’re running and find similarities maybe there’s a better chance to nail this down.
@phoe-nix-art - In terms of ‘unofficial’ blender add-ins - only four - I’m on a new install :
Import-Export : Web3d X3D/VRML2 format ( think this still default, don’t remember installing. )
Mesh: Auto Mirror ( Another I think comes pre-loaded with Blender ?)
Object: Bool Tool ( Another I think comes pre-loaded with Blender - didn’t install, just enabled?)
Node : Animation Nodes *** This one MAY be an issue, as it’s still under development.
I was only using it to change text content dynamically though, and had no issues with it in the past. :-/
