User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7) Gecko/20100101 Firefox/4.0b7
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7) Gecko/20100101 Firefox/4.0b7

On all of the menus and dialog boxes the spacing between characters is incorrect. The characters appear to be stuck together.

Reproducible: Always




I am using Windows 7 with Clear Type option turned off. I am also using custom fonts for the menus and window text (Tahoma 8pt).

Is it the exact same profile? Can you please check in the advanced pane of the preferences dialog what happens when you disable hardware acceleration?

Comment 3

Yes, it's the same profile.

When I turned off hardware acceleration, the font spacing is ok. (btw. i am using a ati hd 3470 notebook card on sony vaio)

Reporter, do you have Cleartype enabled on your box? Can you also please check with a fresh profile for Firefox?

The ClearType is disabled. 

I created a fresh profile, but it doesn't help.

Could you also please try with a fresh Windows user? Would be good to know if any settings of your Windows profile is causing it.

Comment 11

[krzysztofmo]

I created a fresh Window user, but the problem persists. I have also updated drivers for my video card, but it didn't help either.

Thanks. Marcia or Juan, do we have notebooks with an ATI Mobility Radeon HD 3470 or similar in the lab?
