The most damning thing for Southgate is that anyone who is an England fan could have predicted that performance and described how the entire game would go before it had even begun. It's incredible that he expects anything else by changing one player and nothing more.

Lots of nice perf panel things in 126! Better UI for hiding tracks, support for ignore lists in the flamechart, and a 20x CPU throttling option ๐ŸŽ‰

This is a fun one. "โ˜ฐ" seems to send the browser looking through a bunch of fonts to find one with the character. When profiling with 6x CPU slowdown, the delay is significant (40ms on a high-end machine), but I don't know how realistic that delay is. issues.chromium.org/issues/3625223โ€ฆ
