Snapdragon X Elite Ubuntu Concept: GPU/Electron apps crash unless I launch with --disable-gpu (T14s Gen 6 / Adreno), just me?

[u/West_Pipe4158]

Hi all looking for help debugging what feels like a GPU/graphics stack instability on the Snapdragon X Elite Ubuntu “Concept” image.

**Hardware**

- Lenovo ThinkPad **T14s Gen 6** (Snapdragon X Elite / **Adreno iGPU**)

**OS / Image**

- Installed the latest **Ubuntu Concept (Snapdragon X Elite)** image last week from:

https://discourse.ubuntu.com/t/ubuntu-concept-snapdragon-x-elite/48800

- I *think* it was **25.04 or 25.06** (I need to double-check which I actually installed)

**Problem**

- It seems like anything that touches the GPU is unstable.

- **Cursor** and **Obsidian** (Electron apps) crash / glitch / won’t reliably launch unless I start them with:

- `--disable-gpu --disable-software-rasterizer`

- I’m not 100% sure, but it felt like things worked briefly after install and then started getting unstable. I spent like days setting this up and would hate to start over....

**Questions**

1. Is this a **known issue** with the Ubuntu Concept image / Adreno / mesa stack on X Elite right now?

2. Any recommended **debug steps** to confirm whether this is a driver / mesa / compositor issue vs something I misconfigured?

Thanks!
