Dealing with a strange problem, which is that kicking off an Eevee render on Debian 12 seems to crash my GPU. Blender hangs on a single pass with extremely broken mesh and then a couple of seconds later the GPU just quits. Monitors lose signal, unrecoverable without a hard reset. Weirdly, Eevee works just fine in Rendered viewport preview mode. But initiating an actual render crashes every time.
System is a Ryzen 5 5600X with a Radeon RX 6700 XT and 32 GB of RAM. OS is Debian 12 Stable with the 6.1.0 kernel and KDE Plasma desktop.
Crash happens with the tarball version of Blender, on a clean install of Debian 12 and KDE with nothing else done to it.
Well, first does that happen on every single scene or just a particular one ?
If otherwise it works then you’re good to hunt down the bug, maybe disable all the objects/ collections and bring them back one by one until you have some crash…
At least from what you say I think there is just an issue in your scene, but maybe it’s a bug, you have to investigate to know more !
Hmmm now that’s really interesting. So far it does seem to be only this one scene. From what I can tell so far, it looks like a problem with a simple particle system I set up for some undersea foliage. It’s a very simple setup that calls from a collection with two mesh assets, and when I turn off rendering of either one the render works just fine. But making both visible, results in the crash when I try to render. Only in Eevee, not Cycles.
Three other scenes I’ve since tried all render in Eevee without any issues, including one very heavy and complex scene with multiple hair particle systems enabled.
Going by the date of this scene I must’ve made it in Blender 2.92. Maybe there was some issue with that particular build? It’s strange that it has never come up before. And it’s only in this new Debian 12 build that I experience the crash error; in Kubuntu 23.10 the scene renders almost instantly with no problems whatsoever. Very weird. But, it does seem to be the case that it’s an issue with the scene, not Blender itself.
Well at least you find out the culprit , now you probably need to study that particle system a bit more to really find out what is causing the crash.
It’s very likely to be a bug in eevee …
I’d say since eevee next is on it’s way it’s probably not worth looking more into it…
Bugs can be strange, I recall one that what making cycles crash when you put a plane right in front of the camera in the center of the screen.
That was making a particular shot impossible to render, but every other ones didn’t had that issue. Fortunately blender devs are quite reactive when it comes to that and that was fixed a couple of days later.
In your case I suggest you investigate a bit more and see if you can make something works without submitting a bug report… At least that’s what I would do !
That’s my plan at this point yeah. Once Eevee Next is out I’ll definitely revisit this file and see if there’s still an issue, and if so then I’ll try to get to the bottom of it, but as long as Eevee works the rest of the time I’m not going to spend time on it until then. Thanks again.
