Description cantabile 2011-12-15 11:53:18 EST
Description of problem:
The lowercase U, V, W, X and Y in liberation sans at 18px and bold are noticeably thinner than the other letters of the alphabet. It's quite distracting. There is a screenshot attached.

It appears to happen only at 18px (bold).

Version-Release number of selected component (if applicable):
1.07.1

Additional info:
I'm using arch linux.

I wonder if it is related to hinting?

Yes, inside fonts width of character is perfect.
There are some other hinting bugs are pending for liberation. i will looks all together.

I tested this with freetype demo program

$ftstring -m abcdefghijklmnopqrstuvw ppem 200 /usr/share/fonts/liberation/LiberationSans-Bold.ttf

(f for forcing autohint, h for disabling glyph hint, up/down for increasing pt size)

If we enable autohint, everything works fine.
I think we should enable autohint in liberation-fonts .conf file.

Comment 6 Fedora End Of Life 2013-04-03 16:30:42 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
