System Information
Operating system: Ubuntu
Graphics card: my GPU is dead
Blender Version
Broken: 3.1.0-beta+v31.4ee4b61dd8d3-linux.x86_64-release
Worked: 3.0.1
Short description of error
Crash when adding Subdivision surface modifier.
My GPU is dead (too much rendering). Removed Nvidia drivers from system.
Exact steps for others to reproduce the error
Note 1: Does not crash if rendering animation from command line
Note 2: Does not crash in version 3.0.1
Note 3: Also crashes in version 3.2.0-alpha+master.ac3f4db71945-linux.x86_64-release
Added subscriber: @hovjdev
Added subscriber: @ThomasDinges
Changed status from 'Needs Triage' to: 'Needs User Info'
What do you mean by your GPU is dead? Blender needs a GPU to function properly with GUI.
I cannot confirm a crash with Subdiv on the default cube, neither with GPU subdivision enabled nor disabled. (Blender 3.1, Windows)
Changed status from 'Needs User Info' to: 'Needs Developer To Reproduce'
Thanks for looking into this. I understand this may be an unusual case.
I attached a screen recording of the crash.
And I copy pasted the output of chrome://gpu/
My case is unusual because my system stopped working if I boot Ubuntu with nvidia drivers.
However I am still able to use my system if I purge all nvidia drivers.
Blender 3.0 works fine. And Blender 3.1 works also fine except for the subdivision surface.
This is my first bug report, hopefully I am following the right procedure, and not bothering you too much with this.
Many thanks

overrideSurfaceFormatRGB8toRGBA8 (Vulkan workarounds) anglebug:6651: Enabled: true
Override surface format GL_RGB8 to GL_RGBA8
padBuffersToMaxVertexAttribStride (Vulkan workarounds) anglebug:4428: Disabled: isAMD
Vulkan considers vertex attribute accesses to count up to the last multiple of the stride. This additional access supports AMD's robust buffer access implementation. AMDVLK in particular will return incorrect values when the vertex access extends into the range that would be the stride padding and the buffer is too small. This workaround limits GL_MAX_VERTEX_ATTRIB_STRIDE to a maximum value and pads up every buffer allocation size to be a multiple of the maximum stride.

looks like this issue is related:
https://developer.blender.org/T95582
Is it resolved for you? I will wait to close this, until you had the chance to check a new build.
I tried:
blender-3.2.0-alpha+master.eabdcdcd44b9-linux.x86_64-release
blender-3.1.0-beta+v31.4932269ec3fa-linux.x86_64-release
The issue is not resolved

Hi @hovjdev , do you get the crash when GPU subdivision is disabled? {nav Edit > Preferences > Viewport > Subdivision > GPU Subdivision}
Also, please don't paste crash logs directly as a comment (upload a file instead)
Are you running Blender on VM?
Added subscriber: @kevindietrich
Changed status from 'Needs User Info' to: 'Resolved'
Missed that report, but was solved by
3bb4597b2d(as indicated by the errorToo many compute shader storage blocks (9/8)in https://developer.blender.org/T96088#1315615).Hi, when GPU subdivision is disabled I don't get the crash.
Will the fix be available in v3.2 ? The March 29 daily builds are still crashing (3.1.1 and 3.2.0).
Love Blender, you guys are doing an amazing job!

Hello:
I saw this error on my machine:
blender-3.1.0-linux-x64
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.4 LTS

I can fetch more info if you are interested to know more about my configuration.
@hovjdev The fix for the original error should be in the builds you are mentioning. If it still crashes, I suggest to open a new bug report.
@jfvillal This doesn't have any information regarding which Blender version you are using. Please try a [more recent build](3.1.2 or 3.2).
