What options do you have enabled in about:tracing? It's possible that documentation is out of date. When I run 64.0.3276.0 with --enable-skia-benchmarking, and select "cc", "cc.debug", and "cc.debug.display_items", I get expected results (screenshot attached). When the problem occurs, could you attach any suspicious developer console errors if any?

OK, the doc is outdated. I selected "cc.debug.picture", not "cc.debug.display_items". Thanks!

I changed that doc to refer to the right thing, as well as https://sites.google.com/a/chromium.org/dev/developers/how-tos/trace-event-profiling-tool/frame-viewer?pli=1 |
