[Chris Sherlock]

Is that OK?

Comment 6

[John Daggett (:jtd)]

Yes, that's perfect, thanks.

Comment 7

[John Daggett (:jtd)]

One more thing, what was the original site these were taken from?  The testcase looks like it uses cross-site font loading that probably won't load.  A Windows 8 preview site perhaps?

Comment 8

[Chris Sherlock]

It was :-) I'm afraid it's no longer up and running, which is why I bissected the original page to reproduce the issue with a reduced test case...

Attachment: Reduced testcase further

Comment 11

[Chris Sherlock]

The problem font is local to my Windows 7 system - it is Segoe UI Light; you can find the .ttf in C:\Windows\Fonts\segoeuil.ttf. 

According to Microsoft: "Segoe UI is the Windows font intended for user interface text strings", see here: http://msdn.microsoft.com/en-us/library/windows/desktop/aa511282.aspx

Note that Microsoft state that I need to have Cleartype enabled to use it, but this is already enabled, and I'm not having any issues with the font in Internet Explorer. The support info tells me that it can't find any cleartype parameters... not sure if this is significant in any way. 

Please note that I've found that it's quite unhappy with a font size of 1.375em.

Comment 12

[John Daggett (:jtd)]

Attachment: screenshot, new testcase with ie9, fftrunk, chrome

Chris, could you take a screenshot like this one on your machine?  I.e. to compare IE9, Firefox and Chrome together in one screenshot.

One thing to keep in mind is that both IE9 and Firefox running on your machine use DirectWrite while Chrome uses GDI.  But it's curious that IE9 is not identical to Firefox in this case (at least with trunk).

Comment 13

[John Daggett (:jtd)]

Also, what version of Segoe Light do you have?  Go to the fonts folder, open the Segoe UI family, then right-click on Segoe UI Light.  One of the tabs lists the version.  I have version 5.00 on my machine.

My guess is you have something similar but I just want to confirm that.  Microsoft periodically re-hints their fonts which could potentially affect the results here.

Comment 14

[Chris Sherlock]

I'm actually using IE8 at the moment - but the difference is fairly amazing! Sending it over. Will also upgrade to IE9.

Font file version is 5.00 according to the file metadata.

Comment 15

[Chris Sherlock]

Attachment: Firefox 13, Chrome 20 and Internet Explorer 8

Comment 16

[Chris Sherlock]

Let me create a restore point before I upgraded to the latest version of IE. I've (unfortunately) got an app that I sometimes work on that relies on it (ActiveX controls and non-compliant js... don't ask).

Comment 17

[Chris Sherlock]

Oh brother. I suspect that I've led you all on a wild goose chase. I'm installing IE9 now, if I get the same font issue with that I will be most embarassed!

Comment 18

[Chris Sherlock]

It appears that there is nothing wrong here. The issue is not with Chrome or Firefox, but seems to be something to do with the font. I'm dreadfully sorry for wasting folks time on this one!!!

Marking this as RESOLVED INVALID.
