+;agenda
+* Do we need this meeting?  Last time we met, we decided we needed at least one more.  Is this it?
+===8/27/13===
+;agenda
+* Early performance measurement results
+;status
+bjacob:
+* GfxInfo/Gonk stuck, with some retest fixes, it also regressed WebGL on B2G
+* deploying emulator fix - nontrivial because of Git issues (mwu helped us with updating this)
+* strategy for the tests
+pchang:
+* B and R swap landed
+* looking at the canvas issues, FishIE, flushing, ...
+snorp:
+* (how do we set the cache size? we want to re-run the benchmark tests with the cache size set to a larger amount than
+george:
+* looking into fixing https://bugzilla.mozilla.org/show_bug.cgi?id=903993 (SkFontHost crash when using flash on Android)
+===8/20/13===
+;status
+* snorp
+** going to uplift changes to 25
+** will fix crashtests tomorrrow
+** patched crash from demotion
+* peter
+** deferred rendering
+===7/30/13===
+;status
+* peter
+** 894847 failed to launch everything.me with skiaGL canvas - Fixed
+** 899408 Fail to enable skiaGL canvas because white list checking
+** profiling "cut the rope" on mac and b2g
+* snorp
+** Issue on PowerVR is figured out
+*** with non-power-of-2 texture we're copying to a power-of-two texture and then doing a readback
+*** the copy was busted. Adding a flush fixes it
+** with that fix, plus fuzzying we pass tests
+** fuzzing is controversial
+** snorp is working on a gl test app to prove or disprove gl hardware munging colors
+* george
+** trying to get API trace working
+** investigating errors exposed by advanced blending demotion
+* bjacob
+** looking at enabling on b2g
+** mochitests on try, pretty good. A couple unexpected pass and a couple off-by-ones
+** on official canvas2d test suite, there is a color channel swapping error {{bug|899798}}
+;next
+* snorp to finish gl color munging test and we'll discuss on #gfx tomorrow
+===7/23/13===
+;done
+* Travel to Skia/Google offices in North Carolina - Aug 5-7
+* peter
+** Memory usage of skiaGL on Bug 864222
+*** Looks like fixed at m-c new rebase skia, will check the detail
+** Found the root cause of GL-rendering fps slow on bug 894847 (also happened to 2D canvas)
+*** Was caused by async canvas update on b2g
+** Check any other skiaGL issues on B2G
+* snorp
+** pref'd on by default for tegra on android
+** next up is PowerVR {{bug|896670}}
+* george
+** new version of skiaGL doesn't support advanced compositing with ES2
+* bjacob
+** working on GL multipleing
+;next
+Order of things to do:
+# Fall back for operations we don't support (george)
+# fix for non power of 2 (snorp)
+# pref on for b2g (bjacob)
+# GL multiplexing (bjacob)
+# advanced compositing
+===7/9/13===
+;done
+* snorp
+** landed
+** working on test failures to turn it on
+** we're OOM'ing on tegras
+*** setting cache to 8 textures of 8MB makes things pass
+*** we should set a small cache size for reftests
+** there are still a couple of failures, should be fuzzable
+* peter
+** looking at fishIE thrashing
+** backed out patch from bug 875555
+;next
+* put the skip-if in for the last failure in R2
+* fuzz the failure in R4 and 3 of the tests in R2
+* investigate the failure in R3 and the first failure in R2
+* fix skia-npapi
+===6/25/13===
+* Snorp filed bugs on all mochitest failures
+** matt has patch for shadow failures, thought not a complete
+** snorp has patch for clip winding failures
+** composite failures are due to Skia not implementing advanced blend modes
+* George
+** working on a new rebase
+** image rendering tests are also failing
+** will evaluate new rebase to fix advanced renders
+*** if more than a days worth of work, will land current rebase
+*** otherwise we'll land the current rebase
+*** either way the plan is to land this week
+* Peter
+** FishIE got better on Graphics branch
+** trying out Skia debug canvas
+* Benoit
+** found shutdown leak with valgrind
+** backed out the patch from matt woodrow
+;plan
+* land current skia rebase tomorrow
+* image encoding failure we'll mark as fails

 ** fishIE tank
 *** can see fish
-*** 22fps
+*** b2g got 12 fps and the main thread was blocking by DrawTargetSkia::Flush

 *** failed to talk to vlad
 *** might need to move mochitests to reftests
+** Will schedule time with vlad and bjacob to figure out what we want to do with tests
+* george
+** getting us into a landable state
+** investigating a failure on a gradient test with software skia on windows
+* bjacob
+** refactoring ownership model
+** see notes for model
+** fixed memory leaks and crashes
+*** {{bug|884034}} Matt Woodrow thinks we're wallpapering over one of the bugs, require a different patch
+** webkit and skia initialize ref counts to 1, which is an impedance mismatch with gecko
+* next steps
+** snorp, vlad and bjacob to talk about test failures
+*** snorp will arrange
+** george will get the graphics branch green
+** peter will look at the wrapping issue in fishIE
+** peter will use nexus 4 to compare chrome and gecko performance
