line-height problem when using ž character

  • 772

If I write a line containgin ž in konsole or kwrite, the line height gets messed up. Is the default font broken, or is it the apps? Didn't know where to report the bug, so "ask ubuntu" sounded as a good start.

How to reproduce:

  1. Open kwrite, kate or console
  2. Write __
  3. Then add a ž on the same line so you now have __ž

Expected behavior:

  • The other chars should stay the same when I add a ž

Current behavior:

  • The __ is no longer visible, guess all text get their lowest pixels removed, the _ char only have lower pixels, so easier to spot there.

In konsole, the cursor position make some differences, think it draws the text in 3 parts: before, on, and after cursor, so only the parts that include the ž char gets the error, if you wirte __ž__ and put the cursor on the ž char, you can see the __, but if you write __ž__ž__ you can see the 3 different parts acting.

Screenshoots as requested, first from Konsole:

4 screenshoots from konsole

In the screenshoo i first wrote: __ž__ž__ and then just moving the curser between the 4 screenshoots.

Screenshoot from kwrite: enter image description here

    I'm able to reproduce same issue on Kubuntu 15.10 (VBox). It is a font problem. It happen with "Oxygen Mono", it doesn't with "Ubuntu Mono" & "Deja Vu Mono".

    1. Find the corresponding font file

      $ fc-match "Oxygen Mono"
OxygenMono-Regular.ttf: "Oxygen Mono" "Regular"

    2. Find the source package and the full path

      $ dpkg -S OxygenMono-Regular.ttf
fonts-oxygen: /usr/share/fonts/truetype/oxygen/OxygenMono-Regular.ttf

    3. Collect info

      ubuntu-bug /usr/share/fonts/truetype/oxygen/OxygenMono-Regular.ttf

      Then send (It will open a link in the browser)

    4. Complete Lauchpad bug report and submit

    If things get slow, You may submit another report to upstream project KDE. Just update both reports to include the links to each others.

    Here a command to show package info including the upstream link...

    $ apt-cache show fonts-oxygen
