Report is clear

LLM Reasoning

Got it, let's see. The bug report has a clear title, a short description of the error, and exact steps to reproduce. The steps are detailed: open Blender, open Image Editor (F11), switch to Paint mode, left click on empty image, crash. So the clarity is good. So the answer should be Yes.

Report is specific

LLM Reasoning

Got it, let's analyze this bug report. The title is "Blender crashes when trying to paint on an empty image". The body describes a specific scenario: crashing when left-clicking on an empty image in the Image Editor while in Paint mode. The steps are exact and detailed (open Image Editor, switch to Paint mode, click). So it's about a specific issue because it's tied to a particular action (painting on empty image) rather than a vague "crashing while rendering". So the answer should be 'Specific'.

Crash on sculpting brush stroke

https://projects.blender.org/blender/blender/issues/157213

System Information
Operating system: Linux-6.19.9-200.fc43.x86_64-x86_64-with-glibc2.42 64 Bits, WAYLAND UI
Graphics card: AMD Radeon 780M Graphics (RADV PHOENIX) Advanced Micro Devices radv Mesa 25.3.6 Vulkan Backend

Blender Version
Broken: version: 5.2.0 Alpha, branch: main, commit date: 2026-04-10 23:18, hash: 2229dfdf760c
Worked: (newest version of Blender that worked as expected)

Short description of error

  • Use a brush on empty space in sculpt mode -> Crash
LLM Reasoning

Got it, let's analyze the two bug reports. First, look at the "Description of issue" and "Steps to reproduce".

Bug report 1: Crashes when left-clicking on an empty image in Image Editor (Paint mode). Steps: Open Image Editor, switch to Paint mode, click empty image → crash.

Bug report 2: Crash when using a brush on empty space in sculpt mode. Steps: Use brush on empty space in sculpt mode → crash.

The contexts are different: one is Image Editor (painting an image), the other is Sculpt mode (3D sculpting). The actions and modes are distinct. So they're not the same issue. Therefore, the answer is No.

Instant Crash when switching to Texture Paint

System Information

Graphics card: NVIDIA GeForce RTX 2070 Super NVIDIA Corporation NVIDIA 570.124.06 Vulkan Backend

Blender Version
Broken: version: 4.5.0 Alpha, branch: main (modified), commit date: 2025-03-27 17:57, hash: d3d776fd3cac
Worked: Blender 4.4 and before

Short description of error
Blender instantly closes / crashes when switching to the Texture Paint layout
Also happens under Windows

Exact steps for others to reproduce the error

  • Open Blender and either use the default cube or add a new one and select it
  • Go to the Texture Paint layout
  • Crash
LLM Reasoning

Got it, let's analyze these two bug reports. First, look at the descriptions and steps.

Bug report 1: Crashes when left-clicking on an empty image in Image Editor (Paint mode). Steps involve opening Image Editor, switching to Paint mode, clicking empty image.

Bug report 2: Crashes when switching to Texture Paint layout. Steps are going to Texture Paint layout, which might involve different modes or contexts.

The key difference is the trigger: one is clicking an empty image in Paint mode (Image Editor), the other is switching to Texture Paint layout. The error descriptions mention different actions leading to crash. So they're not the same issue. Therefore, answer is No.

LLM Reasoning

Got it, let's analyze these two bug reports. First, look at the key sections: description and steps to reproduce.

Bug report 1 has a clear description: Blender crashes when left-clicking on an empty image in Paint mode. The steps are specific: open Image Editor, switch to Paint mode, click empty image, crash.

Bug report 2's title is "art-up crash with vulkan", but the description and steps are missing (they have placeholders). So we don't know what the actual issue is for bug report 2. Since we can't compare the details (like the specific action causing the crash or the context), we can't say they're the same. The first has concrete info, the second doesn't. So they aren't duplicates.

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

Exact steps for others to reproduce the error

  1. In the default file press F12 to render

Blender is launched as:
.../blender --no-window-frame --debug-memory

LLM Reasoning

Got it, let's analyze these two bug reports. First, look at the description and steps.

Bug report 1: Crashes when painting on an empty image in Image Editor (steps involve opening Image Editor, switching to Paint mode, clicking). The error is about painting on empty image causing crash.

Bug report 2: Crash when pressing F12 to render. Steps are just pressing F12 in default file. The issue here is rendering, not painting or image editing.

So the issues are different—one is about painting in Image Editor, the other about rendering with F12. Therefore, they are not the same issue. So answer is No.
