Update to bugfix release 2.10.8 in Xenial

[Amr Ibrahim]

This is a bug fix release in the stable 2.10 series.
http://webkitgtk.org/2016/03/11/webkitgtk2.10.8-released.html

What’s new in the WebKitGTK+ 2.10.8 release?

- Limit the number of tiles according to the visible area. This was causing a huge memory consumption with some websites.
- Fix flickering and rendering artifacts when entering accelerated compositing mode before the web view is realized.
- Fix rendering of form controls and scrollbars with GTK+ >= 3.19.
- Fix HTTP authentication dialog rendering when accelerated compositing mode is enabled.
- Fix rendering artifacts when using a web view background color.
- Fix a crash when creating a WebKitWebView without providing a WebKitWebContext.
- Fix several crashes and rendering issues.
- Security fixes: CVE-2016-1726.

Thanks for proposing this update. In general, I strongly recommend updating all supported releases, not just Xenial. See http://webkitgtk.org/security.html for details.

2.10.8 fixes a serious bug that crashes GPU drivers, a source of many complaints from users, so it's an important update. Unfortunately this fix introduced a regression affecting Twitter, so I recommend skipping this particular update to wait for a fix. See https://bugs.webkit.org/show_bug.cgi?id=155426

Iain, I see that 2.10.8-1ubuntu1 is in proposed now. But why is it built with GeoClue 1, while we have GeoClue 2 in main? https://launchpad.net/ubuntu/+source/geoclue-2.0

I also filed Bug #1556964 to update webkitgtk to 2.4.10 in Trusty.

We don't have geoclue-2.0 on Ubuntu desktop.

Hi,

As I mentioned above, 2.10.8 is a known-bad release. It turns out that it broke many sites, not just Twitter. You really do not want to ship with this; you should upgrade to 2.10.9.

[Marc Deslauriers (mdeslaur)]

We have (2.10.9-1ubuntu1) now in xenial.
