konsole: strange font effects when reverse video is used
Last modified: 2010-12-03 22:13:13 EST
Description of problem:
When reverse video is used the text is displaced from the original position.
The problem was not occurring with the same KDE in Fedora 11 (I am not sure whether the konsole version was the same).
See the screenshots.
Version-Release number of selected component (if applicable):
Very oftem, but not always.
Steps to Reproduce:
1. open konsole and display some text (I did "ls -l /etc")
2. select a letter in a word (I selected the 1st "o" in the work "root")
The line starting from the selected text is displaced to the right by a few pixels
No text displacement should happen.
GTK+ widget style in use
Liberation font family in use
I upgraded from Fedora 11 with the "preupgrade" script.

By changing the font to anything buy "Liberation mono" I get the problem fixed!
GTK+ widget style in use
I'd highly recommend not using that in KDE. It's provided primarily as a fallback style for qt/kde apps running under gnome to look more native.
We've had intermittent reports of text disappearing over f12 development cycle, and oftentimes, it was attributed to video driver issues.
What video hw/driver are you using?
I am using Nouveau (nvidia)
And switching to a different *KDE widget style* won't afftect the problem. Only changing the font away from Liberation Mono.
It looks like this font, while claiming to be monospaced, for some reason actually isn't. I'd blame either qt for misrendering the font / miscomputing character widths or liberation-fonts for just being broken. We need to figure out which package is at fault.
(See the second attachment - https://bugzilla.redhat.com/attachment.cgi?id=370123 - for evidence of that "not really monospaced" effect.)
This bug has been triaged
Fedora Bugzappers volunteer triage team
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
