Reproducible: Always Steps to Reproduce: 1. Go to http://www.w3schools.com/css/tryit.asp?filename=trycss_border-color 2. The css examples here should show the problem. 3. Try the same page in Firefox 3.6 Actual Results: Borders are rendered with a break at the corner Expected Results: border corners should meet.
Cannot repro on WinXP. To test if this is an D2D Rendering Issue, check "about:support" very bottom "Direct2D Enabled" Status. Test against setting "mozilla.widget.render-mode" to 0 using about:config.
(In reply to comment #1) This only shows with Direct2D enabled.

Looks like we lose the beveling on one end of the border there somehow. Bas?

looks like a dupe of bug 590407
Related, but may not be dup; there are no rounded borders here.

Ever confirmed: true
Huh, I can't reproduce this. In the latest nightlies, we have more information about your video card in about:support - Chris, can you paste that here?
I can reproduce it. Adapter Description NVIDIA GeForce 7050 / NVIDIA nForce 610i Vendor ID 10de Device ID 07e3 Adapter RAM 256 Adapter Drivers nvd3dum Driver Version 184.108.40.20621 Driver Date 6-7-2010 Direct2D Enabled true DirectWrite Enabled true
Nvidia 7050 is D3D9.
Adapter Description NVIDIA Quadro NVS 110M Vendor ID 10de Device ID 01d7 Adapter RAM 128 Adapter Drivers nvd3dum nvwgf2um Driver Version 220.127.116.1167 Driver Date 3-6-2009 Direct2D Enabled true DirectWrite Enabled true
These are all DirectX 9 parts; we don't officially support those, so this issue can't block.

Do we need to blacklist them, then?
No. These users have turned on D2D explicitly; blacklisting is for where it causes more pain than just bad drawing.
Oh, I see. So is the plan to default d2d off on unsupported hardware but allow users to override?
Right. ("Allowing" users to override really just means not disallowing them from overriding.)
I believe this is now fixed.

Created attachment 494904 [details] Connected D2D borders This is working for me now with the landing of bug 588271, D2D Nvidia 7050.
Closable as WFM/Fixed by Bug 588271 then?
