When debugging OpenGL on WSL2 i'm seeing this error message:
[default] [error] OpenGL Debug message:
id = 1
message = GL_INVALID_OPERATION in glDrawElementsInstanced
source = GL_DEBUG_SOURCE_API
type = GL_DEBUG_TYPE_ERROR
severity = GL_DEBUG_SEVERITY_HIGH
It appears to happen specifically when rendering with both mesh normalsand one of the following options enabled:
XZ Grid
XY Grid
YZ Grid
Axis Lines
AABBs
BVH
The commonality between those options is that the ultimately cause the renderer to use GL_LINES rather than GL_TRIANGLES. That's problematic when Mesh Normals are enabled because it uses a GPU-based geometry shader, which assumes GL_TRIANGLES input, to render each mesh normal as a little red line in real-time.
