Looks like this is due to https://chromium-review.googlesource.com/830685. sky@, is this size regression expected?

https://chromium-review.googlesource.com/830685 is, for the most part, chromeos specific and shouldn't impact windows. I would not expect an increase in windows from this change. Are you sure you have the right regression range?

Sorry; it is actually the commit before yours: https://chromium-review.googlesource.com/704262. I don't know why one of the graphs (win-32) points to your change.

I verified the size increase between r524492 and r524493 locally. Then I reverted to r524492 and applied all the changes from r524493 except for chrome/browser/printing/print_view_manager_base.* and the size hasn't increased. So something in PrintViewManagerBase is causing this. We'll need to dig into the changes there and figure out why.

I think this is because we added a PdfMetafileSkia use on Windows that was not strictly necessary.

Remove PdfMetafileSkia use from PrintViewManagerBase on Windows.

It is not strictly necessary and it causes a 200 KB size increase.

There's a green alert firing on the Win perf bot for the size decrease. +miu (current perf sheriff) FYI.
