Wireframe rendering fails on linux with amdgpu drivers
On ubuntu 22.04, with Radeon GPU/APU, and amdgpu drivers, the wireframe rendering is incorrectly shaded. Many lines are black.
For TestQuadricDecimationRegularization, the black lines ruin the rendering completely:
For TestCoincident, the change is more subtle, but is enough to cause a test failure:
The total number of test that fail with amdgpu drivers due to this issue is around 20 (pretty much every test that uses wireframe rendering).
