Description

System Information
Operating system: Linux-5.16.9-200.rog.fc35.x86_64-x86_64-with-glibc2.34 64 Bits
Graphics card: AMD RENOIR (DRM 3.44.0, 5.16.9-200.rog.fc35.x86_64, LLVM 13.0.0) AMD 4.6 (Core Profile) Mesa 21.3.8

Blender Version
Broken: version: 3.1.0, branch: unknown, commit date: 1970-01-01 00:00, hash: rBunknown
Worked: (newest version of Blender that worked as expected)

Short description of error
[Please fill out a short description of the error here]

Example file is a low-poly wood log with edge bevels, creases, and subdivision. This opens on Windows without issue, on Linux the file instantly crashes Blender 3.1.0 (Fedora 35, Blender installed from RPM)

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Try to open the file on Linux, Blender crashes. Windows opens the file without issue. If file is opened on Windows, and subdivision modifier is disabled, the file opens on Linux. Enabling subdivision on Linux causes an instant crash.

Does this also crash without GPU subdivision preference?


And could you also check a fresh 3.2 build from https://builder.blender.org/download/daily/?

Yes. And the subdivision modifier is not the last one in the stack, so I believe it was using CPU to begin with.
Blender 3.2 appears to fix the issue. Thanks!

Assume this can be closed then?
