I don't think this is true, I think the accents are overlaid in a way
that makes them hard to distinguish.  Try zooming in, if you can.

Hmm... something strange happens with DejaVu Sans Mono.  I tried two
different font backends, and they both display the circumflex
incorrectly.  That doesn't happen with other monospaced fonts I tried.

I have no idea what's going on here, sorry.

In any case, the issue at hand is not about this particular display
with this particular font, it's more general.
