• Perf P2 bug 1174770 - tpaint regressions (3%-8%) in e10s mode compared to non-e10s mode
  • bug 1262946 - Don't focus the initial browser in a new window until it has been painted
    • This had a really great impact on tpaint across the board - ignore the Windows XP stuff, since that's kinda been tainted by the disabling of e10s stuff that happened recently.
  • Really close to the 5% threshold now. cpeterson has given his opinion that we should move on.
    • Hoping to drive towards sign-off of all UI responsiveness borderline regressions, leaving only tps
• Perf P1 bug 1186585 - 19.66% - 44.84% tps talos regression with e10s enabled and APZ disabled
  • I'm reasonably certain the test is flawed in its measurement, and is favouring non-e10s. See my arguments in bug 1261152
  • Currently in the process of re-writing part of tps to be more accurate. Initial results look promising, hoping to have solid data from a try push tomorrow.
• bug 1263887 - [e10s] The dropdown selector is not working properly.
  • We triaged this last Tuesday, and I was asked to do investigation. The problem is that script on the page is mutating the <select> dropdown after it has opened.
• Fixed regression bug 1260461 - Firefox fails to exit on system shutdown
  • This has now been uplifted to aurora / beta. Waiting to hear back about ESR.
• Fixed regression bug 1255773 - Page Info - Media is incomplete
