I don't see any scrollbar on the one attached to this report.

Here is a screenshot showing the problem. This occurred during the end user configuration of an OEM installation.
Screenshot is in French but the problem is exactly the same in English.

in xubuntu the scroll bars are only necessary because of themselves i.e. you only have to scroll through space that is covered by scroll bars. is this a separate bug or a part of this one?

Adding light-themes task for triange.

We are running ubiquity-only mode in special mode (well metacity without compiz/llvmpipe). Some other ~ similar bug reports on the internet (e.g. firefox) with 1px wide scrollbars indicate that this is potentially a theming issue: just-fit contents requires scrollbars, when the scrollbars have a 1px wide border.

Also note that we are getting "fat" gtk scrollbars instead of overlay scrollbars. Do overlay scrollbars require 3D-accel / compositing?

Did you manage to reproduce this problem?
Do you have screenshots and logs?

A recent screenshot would be nice to see. This bug loves to pop up unexpectedly, but I could have sworn it went away with Precise. (At any rate, overlay scrollbars should solve this on their own, so I'm curious that they aren't here).

Did you happen to open and close the Details pane? I have only seen it change the window height so the slideshow stays as it is, but maybe something odd happened.

I can add overflow:hidden to the body element in the slideshow and that should handle its part in this. I'm worried it could cause something unexpected, though, since Webkit is a fickle beast and I'm not sure how the the webview's resizing works right now. Okay if I make that change early on for Ubuntu R?

Huh?!

The scrollbars were broken in the ubiquity-only mode vs
desktop-session, which I have now fixed. After I did that fix I've
asked to retest for this bug, because the available screenshots of the
bug were: from ubiquity-only mode & ubuntu flavour only.

The reason they were broken is because they moved from being an
automatic LD_PRELOAD to become a proper gtk module and hence required
changes to ubiquity-dm.

I didn't want to spell out this over here, because we never found out
the root cause for this bug, hence the speculation that changes in the
scrollbars were causing this.

At any rate, the webkit webview & the scrollablewindow port & the whole ubiquity-only session is all code in the ubiquity and not in the slideshows.
