  • Working on bug 1262671 to further address OOM issues in IPC code.

bsmedberg

gw280

  • Mostly working on using firefox.exe for everything. Should have a patch by the end of today or tomorrow.
  • Per-process texture pool: have some preliminary patches and some good feedback from nical and mattwoodrow. Working on this in the background.

haik

  • Landed bug 1258925 ([e10s] Browser window is resized when click)
  • Working on bug 1248683 ([e10s] Find bar sometimes gets keypresses in the wrong order when system is under heavy load)

jimm

  • bug 1263951 (crash in mozilla::ipc::TransferHandleToProcess (GMP related)) - patch posted, waiting on review.

mconley

  • M9 bug 1263887 - [e10s] Select dropdowns in e10s mode do not notice changes to the <select> after it has opened.
    • Patch up, waiting on review
  • Perf P1 - Bug 1251699 - 5.7% TART regression on OS X with APZ disabled
    • This has gone away. The remaining TART regression is APZ-related, and a price we have to pay for APZ. See bug 1253412
    • barbara signed off on TART over email
  • In discussions with a number of folks regarding the remaining UI Smoothness Criteria, and whether we want to block on what's left.
    • I think "no", but being conservative and assuming the group will say "yes", and diving full-on into the remaining regressions.
  • Perf P2 bug 1252768 - 2–7% e10s CART regression (with APZ disabled)
    • Linux64 only, and very mysterious. I have about 12 try builds going right now with various experiments.
  • Perf P2 bug 1174770 - tpaint regressions (3%-8%) in e10s mode compared to non-e10s mode
  • Perf P2 bug 1096013 - [e10s] Improve perceived session restore duration
    • Got this working yesterday, where we restore favicons and tab labels way faster, which is nice
    • Also makes it so that background tabs, when crashing, don't lose their favicons, which is even nicer
    • Currently trying to find the best way to do it "right", since my initial solution was hacky at best.
