[OSG 3.6.3+] OpenGL error 'invalid operation' when you change the current cell
This issue is not present in previous OSG releases, so maybe it is worth to do bisect.
An example of error message in the console output:
Warning: detected OpenGL error 'invalid operation' after applying attribute Viewport 0x55efe4312600
APITrace tells that this call
glTexStorage2D(GL_TEXTURE_2D, 1, GL_RGB8, 320, 320)
returns GL_INVALID_OPERATION.
