If I have sp-linear2.ro open in the app and I close any window except OpenGL I get endless exceptions like you. If there is nothing in the scene and I close any window except OpenGL it doesn't happen. Something about destroying and recreating the opengl window (which happens any time Dockables do their thing) puts OpenGL in an unhappy state.

Further in.... Mesh.render() is sad after glBindVertexArray. likely the VAO is invalidated when the window is closed but the Mesh instance doesn't get notified to re-allocate the stale VAO.

I can recreate the bug with a single MeshInstance set to Capsule, then close a tab.
I can recreate the bug with a single MeshInstance set to Cube, suggesting it is any Procedural MeshInstance.
I cannot recreate the bug with a single MeshInstance set to File > femur.stl, further suggesting it is Procedural MeshInstance.

When DockingPanels destroy the OpenGL context, the OpenGL3Panel disposes of all cached assets and recreates them at the right time. Procedural meshes are not cached correctly and are never disposed. Oops.
