First draw call of the first snapshot seems always to have really large number as the 'clocks' value.
This one snapshot that I just took has about 4 gigacycles marked for the first draw call. It's not an issue
on it's own because the 2nd snapshot (if you can take it) shows more realistic values, but I have some
content where I'm unable to ever get the 2nd snapshot without the app crashing / getting stuck.
If the cycles count was correct for the first snapshot, then I would get a clean trace on the first attempt and
be happy about it :-)
