It doesn't work as well if you acknowledge that was the motivation ;-) (j/k)
I agree a reproducer is a good idea, but as I mentioned in the
cut part, doing the update area without keeping the monitor waiting
improves performance of the guest by letting it do io exits. Why is that
a bad thing?
You say, "improves performance", but can you quantify that?
And why is screendump on the performance critical path in the first place?
Having a small test case that demonstrates the problem (be it functional or
performance) will help ground this discussion in concrete terms.
I think we need to step back and reexamine what the problem we're trying to
solve is.
