Thanks for the report, but this is known issue - apply transform is broken in many cases, that’s why it’s tagged as experimental, not considered a bug in current state.
I see, it's not just a string change, the code is slightly convoluted ;)
First round of comments so dalai can start looking into those. more will come as I work my way through the manual:
EDIT: If I set the master scene to the same aspect ratio the resulting image will be too narrow, or is there a way to directly enlarge the render size after render?
I want to render side by side, and the result of each "eye" will be shrinked to half resolution, so I didn't see a point in rendering it full res and shrink it, if I can use the aspect ratio to render it smaller. I guess I'll wright a script that renders the scenes one by one. Or is there a more simple approach?
Looks driver specific and it doesn't crash, will archive for now.

Thanks for the report, but this is currently not possible in Blender, and not considered a bug, rather an UI glitch (we have hundreds more like that in our UI :/ ).
Now I hope its complete
