Subject Re: Benchmark comparison of classic webview and Chromium webview
Date Wed, 11 Dec 2013 15:03:11 GMT
TLDR before we get too excited: Js perf seems a huge win, but at the moment
html canvas is not gpu accelerated, so canvas based apps are actually not
doing so well.  This is known and high priority for chrome-webview team,
though I am not at all sure if it can be fixed in a minor patch of android

There are several crbugs going into specific details and user complaints if
you want to read them (the comments section of the above blog post is a
good start).

If you want to have a canvas based app in 4.4 that doesn't completely suck,
be very careful which what resolution your canvas is set to, perhaps opting
to leave it in the default low-res css-pixel size mode.  This seems to be
especially biting for cordova apps right now, since they by default run
with targetSDK < 19, which leave chrome-webview in quirks mode where
target-densityDpi is still respected, and apparently our cordova hello
world templates set that wrong by default (or at least interact poorly with
the state of 4.4 webview, I haven't finished investigating that part).
