Even if this is TeX font I'll never touch the source of a TeX font as such a change *requires* normally a rename of the font its self due the common font licences. That is that the orignal font with its original name will stay around. If this is really a problem of the fonts then please report it upstream. Beside this, it seems to be a problem with the used font hinting. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

- Change AntiAlias : No effect - Change forceDPI : No effect

The change I expected to be most likely to have an effect is the sub-pixel type. Did you try changing that, and restarting KDE afterward?

- Change .xinitrc, remove the line 'xrandr --dpi 90.6 : Yes, the underscores now do show. And they still show when I re-add that line. Go figure!

Most people sensitive to fonts find a DPI that is a multiple of 4 (or better 12, or still better 24) works best. That rules out 90 (and 90.6) as favorable to best font rendering. Values below 96 are not recommended except when accurate matching of physical screen pixel density and Xorg/KDE DPI is a priority. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=874072 https://bugzilla.novell.com/show_bug.cgi?id=874072#c15 --- Comment #15 from Felix Miata 2014-07-29 01:20:24 EDT --- The sizes in the KDE font settings panel are not pixel (px) units. Rather, they are points (pt), as one would use in a word processor, or on paper. Don't confuse pt units used anywhere else with those found used for the CSS applied in browser viewports like your comment 12 code. In CSS, pt is an arbitrarily defined size in px that has no humanly predictable relationship to the physical size of anything; while elsewhere one pt (usually, not exactly always) is 1/72 of a physical inch. On a computer display an exact match between actual display density of the screen, and the configured display density of the DE, is required for the size to be an exact physical size a that a pt can represent on a computer screen elsewhere than within a browser viewport. At 90 DPI as forced via your font settings, the 10pt you see in the KDE fonts panel computes to 12.500px; 11pt to 13.750px. What brand(s) and model(s) is/are your display(s) (as already asked in comment 2)? Maybe someone that can match it/them can reproduce. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Almost anyway. I do usually compile my own version of libfreetype: 'define enable_subpixel_rendering 1' in the .spec file. I am not too sure if I needed that with OpenSuse13.1 though. That would mean that quite a few less people have this problem. And my primary screen is an odd one in that it uses vertical BGR. I'll do a test with horizontal BGR as well.
