The regression is due to recent changes in libvpx, a fix will get in on the next roll, within a week. Will update after the next roll when graphs recover.

Most of the regressions have recovered from the last roll.
The remaining regressions are on the screenshare_vp9_2sl test, which is a known issue. Marking as fixed.

Assigned corresponding improvements to this bug. Thanks for solving this.
