953253 - overflow:hidden issue on Firefox 26 on Windows 7

Status: RESOLVED DUPLICATE of bug 953334

(Core :: Graphics, defect)

Description

[miika.langille]

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release)
Build ID: 20131205075310

Steps to reproduce:

Consider the following jsFiddle: http://jsfiddle.net/2DF8w/4/
If you open it in Firefox 26 on Windows 7 SP1, then the text inside the treeview breaks out of the overflow:hidden container. Older versions of Firefox, or then on Windows 8, it works just fine. No other browser reproduces this issue.

Note that the results pane needs to be expanded to make the treeview visible. More details can be found on this stackoverflow post: http://stackoverflow.com/questions/20798690/overflowhidden-bug-in-firefox26-on-windows-7


Actual results:

The text of the treeview breaks outside of the container.


Expected results:

The overflowing text should be hidden.

WFM with FF26 on Win 7.
Could you test with a clean profile, please.

Unfortunately the support page is in finnish, but everything should be in the right place.

I can repro.
user_pref("gfx.content.azure.backends", "");
user_pref("layers.prefer-d3d9", true);

Sorry, this is my first time reporting a Firefox bug. Alice, are you saying you you've been able to confirm this as a bug?

Tracking as this is a recent regression and passing it to :Benwa given its possibly a fallout from 907544.

I can't seem to expand the results pane. Is the fiddle broken?

Right click on results pane and select "This Frame" > "Show Only This Frame"

Right mouse button click on the right-bottom pane in order to pop up browser's context menu.
Then, select "This Frame" > "Show Only This Frame"

Does this bug still occur now that bug 953334 is fixed?

bug 953334 is not landed Firefox27.
So, I cannot test.

Marking this fixed on Firefox 27 given 953334 was uplifted. Please re-open if this is still unresolved for you
