Sounds like the app should need to rebuilt it's shader cache? If you
know where it's located, you could try removing it.

Title:
libglx-mesa 24.0.9: shader issue in Electron three-based 3D graph
Status in mesa package in Ubuntu:
Incomplete
Bug description:
On a laptop with Ubuntu 24.04, after updating from 24.0.5-1ubuntu1 to
24.0.9-1ubuntu1 on the 2024-07-22, an Electron-based application,
using a 3D graph based on three.js, stopped working properly. The
Chromium developer tools indicated errors such as:
```
node:internal/process/task_queues:140 THREE.WebGLProgram: Shader Error 0 -
VALIDATE_STATUS false
Material Name:
Material Type: MeshLambertMaterial
Program Info Log: Location of variable pc_fragColor conflicts with another
variable.
```
And other related messages, such as shader issues, appeared as well.
The graphs were no longer visible on the Electron component. When
switching the node type to HTML-based node, it was visible, but the
edges remained invisible. Node positioning and moving was unaffected,
everything seemed normal except that the rendered graph was not
visible.
After downgrading back to 24.0.5, everything works normally once
again.
It is a Dell laptop with Intel Core i7-13800H and NVIDIA RTX A500.
Trying to update its drivers did not help. Visiting
https://threejs.org/docs/scenes/material-
browser.html#MeshLambertMaterial with Chromium (to try and emulate the
issue) did not produce any problems.
