What color/material property exactly are we talking about? (Screenshot might help here)
Has this worked in previous versions?

@Stefan-36 I'm unable to reproduce the problem with either 3.5.1 or 4.0, could you describe the problem in more detail? Or could you try blender -d or blender -d --debug-value 4000 to log some line art related outputs and share the crash log? Thanks!

I'm still unable to reproduce the crash with the exact same version of blender and the provided file. This could probably be a problem related to texture and somehow the drawing state can be messed up. (Provided file doesn't come with packed texture so maybe that could be a difference). The video card seems to be adequate.

Hi, unable to replicate either. Textures are missing in your file.
Please pack them then re-share file with us: File > External Data > Pack Resources -> save .blend file

change the color of the background.

you mean world shader output?

I'm attaching the blend file with external dependencies packed inside.

It turns out that this step is not needed.
Just selecting the line art causes the crash.

I installed blender on a different PC with Nvidia GTX980.
Same installation options (Flatpak provided in Linux mint software center)
I was able to recreate the crash on the first try.

Although not very likely to fix it, but I believe you should try blender downloaded from blender website instead of flathub, depending on how they pack the libraries, it might interfere with the graphics side of blender.

Could you also try packing texture and upload blend file here like @PratikPB2123 suggested? Thanks!

Please see previously uploaded isometric-lineart13.blend that has the packed textures.
I will let you know what happens with the downloaded version of blender.

I downloaded Blender 3.6.0.
The same things happens, crashes when I select the line art.

mesh.validate detected the invalid mesh data: CustomDataLayer type 3 which isn't in the mask

Uploaded file would select line-art object without crash, can you check?

I also tried isometric-lineart13-updated.blend and it did not crash.
But after working with blender for a bit longer on the file, the behavior returned.

#109372 (comment) : mesh.validate detected the invalid mesh data

Guess we can't do much since crash is due to invalid geometry?

  1. The application should not crash even if there is invalid geometry.
  2. If the application is generating invalid geometry, this is also a bug.
    @PratikPB2123 was able to fix the file and avoid the crash, but after some time using the fixed file, the geometry is corrupted again.
    Please note that I'm using a plain install of blender with no additional customization or plugins enabled.

That is not how we handle such crashes, see https://wiki.blender.org/wiki/Process/Bug_Reports/Triaging_Playbook under "Complete report, but corrupted mesh"

  1. If the application is generating invalid geometry, this is also a bug.

Yes, but we need a way to reproduce this corruption

@PratikPB2123 was able to fix the file and avoid the crash, but after some time using the fixed file, the geometry is corrupted again.
Please note that I'm using a plain install of blender with no additional customization or plugins enabled.

Do you have an idea what might have caused the returning corruption?
Any particular modeling operation for example? (e.g. "Join" has been mentioned in relation to mesh corruption, but afaict, this has never been able to be reproduced consistently)

So unless we have a clear way to reproduce the mesh corruption, will set this report to "Needs Information from User".
Please try to find a way to reproduce this, would be great help! Thx in advance

So you can check mesh corruption with (check the commandline for output)

import bpy

for mesh in bpy.data.meshes:
    print(mesh.name)
    mesh.validate(verbose=True)

@PratikPB2123 : I am confused though, your isometric-lineart13-updated.blend still gives me

however, it does not seem to crash...
Have you done anything else to avoid the crash?

  • So unless we have a clear way to reproduce the mesh corruption
  • you can check mesh corruption with (check the commandline for output)

Hi, any updates here? @Stefan-36 ^

I think without clear ways to reproduce the crash or the corruption, it seems this report is stuck and cannot be processed further.

Feel free to open a new report if repro ways can be found.

Will close for now, thx everyone for your efforts here!
