[VTK 9.0.0] Rendering issue (many artifacts) with Nouveau driver

Hello,

I am experiencing issues with rendering (many artifacts) with VTK 9.0.0 (including the latest commit from master) when using the default Nouveau driver on Ubuntu 20.04.2 LTS. This issue does not occur with VTK 8.2.0 nor ParaView. On the other hand, the latest Nvidia proprietary driver works with VTK 9.0.0.

Below are the renderings I am getting when running two examples:

TriangleColoredPoints:

TriangleColoredPoints (rotated):

7b08677c1fea95b8b0abf3ff1860cc421573826a

ColoredPoints:

f877ce77933f88004f6394decad611150f976b50

My OpenGL info is:

OpenGL vendor string: nouveau

OpenGL renderer string: NV124

OpenGL core profile version string: 4.3 (Core Profile) Mesa 20.2.6

OpenGL core profile shading language version string: 4.30

GPU: Nvidia GTX 970
