They don't look bad (actually, it's better than the Q-DOS does), but the shape of the left/right bokeh needs to be the same for the effect to be really nice. For example, this is a particularly good example of what's wrong with just covering opposite halves of the aperture with different color filters. Here's a crop of one OOF PSF from that image:

Basically, in stereo viewing the bokeh shape ends up overlaid half circles, which looks very unnatural.

Maybe one can add an opaque mask with max-diameter circle inside each halve? E.g. glue to the rear-side the filters and the mask?

I prefer front-mounted filters, but the same thing can theoretically be done in front, behind, or at any of several places within -- there are various points where appropriately-sized openings will behave as apertures. The trick is correctly sizing the two circular holes.

Notice that the anaglyph effect is quite good (very little vignetting), but there's nothing sharp in the Q-DOS mode.

Q-DOS lens is 70-210mm. With such long focal lenses vignetting gradually went away in my experiments too. Though your advice on vignetting mask was always beneficial.

Well, yes and no. Fast normals and wider often vignette a lot, but so do many telephoto lenses. The Q-DOS says it only works in the 135-210mm range, and that's largely because the lens doesn't vignette much at all in that range. Most telephoto lenses I've tried still need to be stopped down a bit to avoid vignetting.
