[TM2] 3D stereo screenshots not working

[Xevious]

I have been trying to make 3D stereo screenshots with the editor, but the screenshots look like the attached picture. 3D stereo also keeps anti-aliasing from working in screenshots. You can tell if you zoom in on the picture. My graphics card drivers are up to date and the maniaplanet launcher is set to the default settings. Does anyone know what the issue is? Thanks in advance.

Specs:
Graphics card: MSI R9 270
Processor: Intel Core i5 3570k
Ram: 16 GB RAM
System: Windows 8.1
