Does disabling the hardware acceleration under the preferences | advanced helps here?
Yes It did fix it, but should that happen? Are you working on it? Thank You
resolved fixed? :) are we sure about that?
Good point I will change description
It happens only with hardware acceleration
Please post the graphic section from about:support

Can you please upgrade your driver, i think there should be a new one from nvidia. and of course enable the hardware acceleration back on if you test the new driver
I can confirm this bug using Firefox 4.0 Beta 7. With activated hardware acceleration _all_ drop down menus on websites are broken. Disabling HW acceleration "solves" the issue. I'm using Windows 7. I'll attach a screenshot illustrating the issue. about:support (HW accel disabled): Grafik Karten-Beschreibung NVIDIA Quadro NVS 295 Vendor-ID 10de Geräte-ID 06fd Karten-Ram 256 Karten-Treiber nvd3dumx,nvwgf2umx,nvwgf2umx nvd3dum,nvwgf2um,nvwgf2um Treiber-Version 126.96.36.19921 Treiber-Datum 6-7-2010 Direct2D aktiviert false DirectWrite aktiviert false GPU-beschleunigte Fenster 0/2

Confirming based on screenshots and ask for blocking so it can be investigated. Matthias, is it the latest version of the graphics driver, which you have installed?
No, the driver is from 6-7-2010, as you can see from the about:support text in comment 11. This is my workplace computer, I will install the latest nvidia driver and minefield nightly tomorrow to check if the problem persists. Oh btw.: It's a x64 machine, if that matters.

It just occurred to me what a support nightmare it becomes when users experience rendering bugs in fundamental things like drop down overlays because they have installed a bad combination of graphics card and driver. Sooner or later Firefox will have to implement a mechanism which reminds users that they should install a newer driver to avoid certain bugs...

CC'ing some more ppl to check how we could handle those situations. @Andy: Can you also please upgrade your driver to the latest version and check again with HW acceleration enabled?

Geräte-ID 06fd Device ID 0a6c Device ID 0640 We might need to do some blocking here, but we need to investigate first. Stuart apparently sees this problem on his computer too. We should also ask NVIDIA for information about this; particularly, whether they've intentionally fixed problems related to this in their latest drivers. One thing that people can help us with is finding out whether it's a particular part of hardware acceleration that causes this bug. Disable Direct2D only and see what happens?

Disable Direct2D only and > see what happens? I see this bug. It's annoying to say the least. When I set gfx.direct2d.disabled to true, my drop down menus appear normally.

Unfortunately I cannot install the drivers I downloaded directly from nvidia, and the Lenovo system drivers have not been updated by Lenovo yet. Thank you Lenovo. I love it when you don't let me update my drivers.
Bas, were you able to get information from NVIDIA on whether they intentionally fixed anything, so we can block older drivers?
Created attachment 497927 [details] [diff] [review] Set GDI Compatible flag on swap chain This appears to be a driver problem. We can work around it by setting the GDI compatible flag. Since this should have no negative effects I believe we should just do this.

However I'm seeing the issue still on a ATI Radeon HD 3600 Series.
Truth, please file a new bug and add the graphic information from the troubleshooting page in the comment. Thanks.
Wait. Lets reopen bug 603793 in that case. Haven't seen that your bug has been duped.
The evidence suggests drivers were at fault for me too. This ticket's symptoms (and quite different ones with the whole window - bug 614846) aren't present for me in last night's build (2010-12-22), so I assume the patch here did the trick. I then upgraded nvidia drivers and found these 2 issues went away in 4.0b8 too. - NVIDIA GeForce GTX 260 - old driver: 220.127.116.1145, date 4-3-2010 - new driver: 18.104.22.16896, date 7-9-2010 Thanks all.
