I have an error message (which is mostly a warning, not so much an actual error).
using glDebugMessage(), the error ID that is returned in decimal is 131186 (the error ID is the same class of enumerators as GL_NO_ERROR, GL_INVALID_ENUMERATOR...).
I want to read about the documentation of this value, but I seem to not be able to find it by searching it up. It's not an official OpenGL enumerator value, so i assume it to be driver specific (NVIDIA).
EDIT:
The full message is:
Source: GL_DEBUG_SOURCE_API
Type: GL_DEBUG_TYPE_PERFORMANCE
ID: 0x20072
Severity: GL_DEBUG_SEVERITY_MEDIUM
Message:
Buffer performance warning: Buffer object "SSBO" (bound to
GL_SHADER_STORAGE_BUFFER, and GL_SHADER_STORAGE_BUFFER (3), usage hint is
GL_DYNAMIC_DRAW) is being copied/moved from VIDEO memory to HOST memory.
Does anyone know what this error code means or how to find its documentation?
This warning simply means that OpenGL does not have total control over the SSBO. Because of that, it has to either block/copy the SSBO's data for OpenGL to use it properly. This is slightly inefficient, which is why the driver is warning you about it.
As for the documentation, I haven't really found any. But, I did find this other question which referenced a very similar problem with OpenGL and OpenCL: OpenCL Host Copying Performance Warning
