#3547 assigned defect

Browse: webkit spawns multiple scrollbars in some google apps

Reported by: greenfeld Owned by: humitos
Priority: Low Milestone:
Component: Browse Version: Unspecified
Severity: Minor Keywords: 13.1.0, upstream, wk2fix
Cc: manuq Distribution/OS: OLPC
Bug Status: Unconfirmed

Description (last modified by manuq)

On some webpages (such as news.google.com) Browse will show the Sugar-style scrollbar, as well as an additional scrollbar immediately to the left of the first one.

This has been seen on XO-1.5 and XO-1.75 with OLPC 12.1.0 os8. Also seen in Epiphany, so it's a WebKit issue.

  • Milestone changed from Unspecified by Release Team to 0.98

This seems very specific to google apps, I can see it in plus and news. Setting as minor bug and posponing to 0.98.

  • Keywords 13.1.0 added; 12.1.0 removed

The scrolled window (with the main scroll bars) is owned by Browse, and the google-specific scroll bars are owned by WebKit. There needs to be some communication between the two so that Browse hides its scroll bars when necessary.

Have we tried working with this API?

Replying to dsd:

I've just tried this:

window_features = self.get_window_features()
window_features.connect('notify::scrollbar-visible',
                        self.__scrollbar_visible_cb)
window_features.connect('notify::statusbar-visible',
                        self.__scrollbar_visible_cb)
window_features.connect('notify::toolbar-visible',
                        self.__scrollbar_visible_cb)
window_features.connect('notify::menubar-visible',
                        self.__scrollbar_visible_cb)
window_features.connect('notify::locationbar-visible',
                        self.__scrollbar_visible_cb)
self.props.window_features = window_features

but those signals are not emitted when I go to http://news.google.com for example, and that page shows its own scrollbar + Browse's Activity one.

This email says that gmail does some tricks with the scrollbars and that is why we are having this issue. I'm not sure how to solve it yet and actually I don't know if it there is a solution.

In the same email this guy talks about 'frame-flattening':

This has been fixed in epiphany webkit 2.

Should be fixed with browse webkit 2.
