text wrong clipping (like in textarea box)
text wrong clipping (like in textarea box) Few months ago I've seen that some text in the page goes clipped wrong by the borders of text-holding element. I thought that someone already filed this bug, but I can't find that. Please see attached screenshot. You can create textarea element like this data:text/html,<textarea> add some text and resize textarea to hit middle of text line. Then somehow click or select text and click outside textarea - part of text will not be clipped by textarea and appears outside. But this is not a textarea bug, I've seen wrong clipped text that been absolute positioned inside a container which have overflow:hidden.
This bug exist in nightly (29) with fresh profile. But can't reproducible in stable Firefox 26.
WFM on: Mozilla/5.0 (X11; Linux i686; rv:29.0) Gecko/20100101 Firefox/29.0 Does this issue occur all the time to you or is it intermittent? It might also be OS-dependent.
On the sessionrestore page it happens every time, in the textarea - it intermittent (it needs few times to select text). I don't have any other OS to check. If you can check it on Windows XP please do so. UA: Mozilla/5.0 (Windows NT 5.1; rv:29.0) Gecko/20100101 Firefox/29.0
Please load about:support and post the info in the Graphics section from that page.

Does the problem also occur if you disable hardware acceleration? (There's a checkbox in Preferences->Advanced. Restart Firefox after changing it.)
Yes, that actually helps. I cant reproduce this on <textarea>, and sessionrestore box looks good now. So, the suspect is direct2d text rendering?

Bug 953334 did fix some clipping related bug, could you test again in a Nightly dated 2014-01-10 or later (when they become available)?
It looks like fixed with this update. Sessionrestore screen looks good, and i cant reproduce textarea bug now. Thanks Mats. You can set this bug as duplicate or dependent of Bug 953334 and so fixed. I don't know the correct way. Can anyone else test it? Just to make sure.
Thanks for the report and for testing!
