Can you post the graphics information from Help > troubleshooting information, and check if you can still reproduce this in safe mode? (Help > Restart with add-ons disabled -- also disables GPU acceleration, hence why I'm asking)

Also, was this working for you on earlier nightlies?

I'm not 100% certain whether it was working or not on previous version. From my friends information he has told me that he wasn't experiencing the problem on osx

You missed out this bit of my question. :-)

(I anticipate a graphics problem, which is probably also Windows-specific, but it's not just that - I checked with a colleague on Windows, and they can't reproduce)

That's strange, it does seem to work in safe mode, give me some time to disable and enable a several plugins to see whether which one specifically is causing this to happen.

Turned out to be the h264 codec "OpenH264 Video Codec provided by Cisco Systems, Inc."
It's running Version 1.0

Uh, really? I would have thought this was an issue with GPU acceleration, see comment #2...

Just a FYI it seems to only be with the following missing characters.

Just have a look at the screenshot :p http://i.gyazo.com/5dd1ab69beb1efd5c74c6f90de96740e.png

Seems to be something to do with direct2d. After disabling it it seems to work fine. I guess the rest is up to you guys ;).

I'm happy to help if you guys need any. Just contact me through email.

Hmm. Remaining question: do you know if this issue started recently? (ie, was it fine on Nightly from, say, a week ago or whatever)

Milan, this seems like a graphics issue if disabling direct2d fixes this... about:support info is here: http://pastebin.com/raw.php?i=cQtdUXaW

[Milan Sreckovic [:milan] (needinfo for best results)]

Fairly new driver, either related to OMTC, or perhaps one of the blacklisting failures.  Tag it as OMTC until we verify otherwise.

Could you try just changing gfx.direct2d.disabled to true and see if that fixes the issue, everything else staying normal?

I cannot reproduce this issue anywhere and haven't seen any other reports of it. This is a very mysterious bug.

I believe that I disabled direct2d by setting the value to true.
I'm currently on my works PC so can't confirm on this, will double check once I'm home.

So I just double checked and I did disable direct2d by setting the value to true and it did solve the problem as I mentioned before.

[Bas Schouten (:bas.schouten)]

That's really mysterious (I have hardware really close to yours). I guess we could just blacklist specifically your device and driver version. But it'd be nice to have at least one other person confirming the issue.

[Sylvestre Ledru [:Sylvestre]]

Bas, we should probably wontfix this one, right?

Comment 19

[Bas Schouten (:bas.schouten)]

Sadly you're probably right.
