I think what's happening is that you're hitting this line here, which
breaks out of the loop early:


If you use -i, it won't hit that line.

You're saying that you expect the result with "-i 1000" to be the same
from one invocation to the next? It may not be the exact same, but
close. What are you seeing?

FYI, I've never ran cairo-perf on windows (and haven't heard of anyone
running it lately), so maybe you're hitting some bug that no one has
come across.

You got this in another thread already...
