--- Comment #7 from Eero Tamminen <eero.t.tamminen at intel.com> ---
> This is an artifact of sending damage events to the compositor quicker. I suspect the issue is that the compositor is rendering more frames during the test rather than the overhead of sending more often

I don't follow how just reducing damage event latency would cause more frames
to be rendered, unless damage events were earlier clumped more together, so
that single compositor update handled multiple events, and now the events are
more spread out so that they get handled separately.

To validate the assumption of damage events causing the issue, one could e.g.
check with xresponse [1] whether the number or timing of damage events changed.

But if you know what the related changes were and are sure it was latency
reduction, notabug sounds fine too.
