On startup console logs 'Invalid framebuffer operation' and 'Invalid value' in splitscreen

[philippotto]

When playing with splitscreen and postprocessing, the following errors appear:

• opengl error 'invalid framebuffer operation' at StateSet::compileGLObjects() compiling attribute
• opengl error 'invalid value' after applying attribute viewport

When deactivating postprocessing, the only the first error appears.

The game play itself is not affected.

for me neither of the errors shows up
however, using splitscreen & postprocessing, the secondary window looks like so:
