Blender Version
Broken: (example: 2.80,

, master, 2018-11-28, as found on the splash screen) 3.6.0Worked: (newest version of Blender that worked as expected) don't know
Short description of error
It happens randomly, but when add a plane (with the existing default cube), and try to resize the plane in rendered view mode, Blender crashes with a fairly high probability.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
I don't know the exact step. It happens randomly. I attach the blender.crash and configuration files.
Cant reproduce/
Not sure if related, but when I did was creating a large plane beneath the default cube, to make sort of a floor. Make the plane very big, and then try to keep resizing it fast.
I changed the size of 4 planes from ~-400 to ~500 with quick cursor jerks within a minute
Issue is specific to Embree on GPU on Windows but I haven't reproduced it with Windows 11 + A750 + driver 101.4369.
The stack trace is different from #109282 but I believe it's related and same fix (still being worked on) should work.
Then, when you fix #109282, I will test this again and close it, if it that fix fixes this too.
I haven't able to reproduce this issue on few machine with Windows 11 + A770 + driver 101.4502 despite all my attempts. Yet, while there are some similarities to #109282 - I suspect that is may be a different issue, so make sense to put some work on this topic without waiting for the fix (for #109282).
But inability to reproduce it makes it quite hard to investigate/fix it, so, @Blender-King, would you kindly run some adiditonal checks on your side per our requests (as it seems that the issue is reproducible only on your setup) on next week?
Yeah. Sure.
I'm not sure if I could call this a "good news", but I think I have found a short way to 100% reproduce the crash, at least on my computer. It turned out that I must render a frame, before resizing the plane, otherwise resizing the plane doesn't crash Blender. Here is my screen recording to show the steps.
A770 + Bleder 3.6: Randomly crashes when resizing plane in rendered view modeto Windows + Intel Arc A770: Crashes if modifying the object after rendering image in rendered view modeI did some more tests, and found that it does not have to be a plane or resizing. Just trying to move the default cube also crashed Blender, after calling "render image" when the viewport is in the render view mode.
To illustrate the problem, I recorded the screen from the beginning by clearing Blender's preferences to the end where the crash happened.
Great, thanks a lot - with a video I have able to replicated this issue on my side. I will work on this topic then.
Thanks a lot for the videos, it's very clear how to reproduce the bug and good catch Nikita: it's indeed a different one than the previously reported one.
I've root caused it down to an issue with embree, I've opened it here: https://github.com/embree/embree/issues/453
You can drop-in the attached embree4.dll in your blender.shared folder. It fixes the issue while we look at the options to get it fixed in official builds.

I applied the embree4.dll above and tested Blender a little, and there still is cases of Blender crashing. One procedure is like the following.
Blender crashes. I cannot find blender.crash file in
temp
, so I don't know the error message.@Blender-King, can you please try to repeat this crash but this time start Blender from the console - and post the last few lines of Blender console output right after the crash?
Thanks for the report. For this flow, considering the moment of the crash, it's 99% sure it's the same issue as 109282.
The output was "Abort was called at 27 line in file:"
Yeah, it seems that the output is the same. So, just leaving Blender in the rendered view mode seems to count as rendering.
Reopening until the libraries are updated accordingly in the deps, so fix shows up in blender.org builds.
This is fixed in latest Blender 4.0 builds: https://builder.blender.org/download/daily/ on both Windows and Linux. Not yet in 3.6, it's expected for next update (3.6.2).
fix landed in 3.6.2:
