This may help you figure out what is going on: The big change in v3.4
was rendering the markers in CANVAS.
http://code.google.com/p/gmaps-api-issues/wiki/JavascriptMapsAPIv3Changelog

Not sure how to get your custom overlay above the CANVAS but that
might work, is there a reason why you need to have some native markers
and some in your custom overlay?

Another option would be to try setting the "optimized" property of the
markers to false:

(from the documentation)
optimized       boolean         Optimization renders many markers as a single
static element. Optimized rendering is enabled by default. Disable
optimized rendering for animated GIFs or PNGs, or when each marker
must be rendered as a separate DOM element (advanced usage only).
