Unable to find actual suspect through code search and also observing no CL's under regression range, hence adding appropriate label and requesting someone from dev team to look in to this issue.

Thanks!

wangxianzhu@, just wondering do you have any inputs here? I see couple of your recent changes here (https://chromium.googlesource.com/chromium/src/+blame/HEAD/third_party/blink/renderer/core/paint/paint_layer_painter.cc).

Thank you!

This has nothing to do with paint_layer_painter.cc. It's about printing remote frames.

Wei, can you take a look?
