[FYI] turning phong shading off (also persists after putting back on) in water examples makes go mouve. (channel swap?) #56

(this is mostly for info, since this is on flatpak runtime/org.fedoraproject.Platform/x86_64/f38 (mesa 23) on wayland, so bug could be there, but it is the same on runtime/org.fedoraproject.Platform/x86_64/f37 (mesa 22) so isn't that new)

only reloading fixes, seems somthing not being reset/cleared in shaders?

Thank you, confirmed -- I can reproduce the problem with very latest view3dscene, on Linux, on at least the files you show in the report:

On a quite different GPU:

  Context requested: automatic

  Version string: 4.6.0 NVIDIA 515.105.01
  Version parsed: major: 4, minor: 6, release exists: True, release: 0, vendor-specific information: "NVIDIA 515.105.01"
  Version in suffix, specific to vendor: major: 515, minor: 105, release: 1

  Vendor type: Nvidia
  Special vendors:

    Mesa: False

  Renderer: NVIDIA GeForce RTX 3050 Ti Laptop GPU/PCIe/SSE2

Indeed toggling "Phong Shading on Everything" makes weird colors, and toggling it back keeps weird colors. Only "File->Reopen" helps.

It's most likely a bug in CGE, not on your GPU, so I definitely want to fix it :)
