Hi Oliver,
As far as I know, we weren’t aware of such a bug, so it’s good to report these things (could use menu: Help… Report a Bug).  I can’t do walleye, but cross-eye camera mode both onscreen and in saved image files works fine for me in the current daily build and latest production release. 
Best,
Elaine
