It sounds plausible to me. Overlaying something onto a hardware-accelerated thing suddenly adds a compositing step to your rendering pipeline, which - usually - requires moving the compositing to your GPU as well, AFAIK.
I just don't buy that any halfway decent hardware acceleration isn't robust enough to handle it. In fact they managed to fix whatever the issue was in a later release, which bolsters the argument that their process wasn't robust enough to begin with. With no other evidence here I'm invoking Hanlon's Razor.
