underlines remain in konsole from previous screen content

[Vik]

Binary package hint: konsole

Use ls or whatever to produce a screenful of text. View a file containing URLs using vi (or less) and put the mouse cursor on the URL so that it is underlined. Use the keyboard to terminate the less or vi session. The underline operation from the URL remains until you move the mouse pointer away.

Screenshot of the zombie underline is attached.

Using x86 Ubuntu 9.04 updated as of 4th Aug 2009
Linux kereru 2.6.28-14-generic #47-Ubuntu SMP Sat Jul 25 00:28:35 UTC 2009 i686 GNU/Linux
konsole 4:4.2.2-0ubuntu4

Version: 3.97.1 (using KDE Devel)
Installed from: Compiled sources
Compiler: g++ 4.2.3
OS: Linux

To reproduce this:

1. Open a terminal tab listing a lot of hyperlinks
2. Hover on any hyperlink, it is underlined.
3. Scroll the terminal, either using the keyboard
4. The underline remains as it is

Another related problem:

1. Open a terminal tab listing a lot of hyperlinks
2. Hover on any hyperlink, it is underlined.
3. Scroll the terminal using the mouse's scroll buttons
4. The underline moves along with the link but does not vanish
5. Hovering on another link now creates another underline below it

I can confirm this strange Konsole behavior in Konsole 4.1.2 compiled on three different computers.

Here's Robert's explanation for this (from bug 154012)

Confirmed. The reason for this bug is that the information about 'hot spots'
(areas of the display containing text of interest) is not updated, for
performance reasons, until the mouse is moved after a change in the display's
contents.

So until you move the mouse the screen won't be updated.

Hi,

I have also seen this issue and signed up to report it. I am not sure about the screen not updating, but definetly the underlines are not updated. Could it be possible that the underline is overlayed ontop of the screen rather than printed along with the text.

Here is how I found the bug.

 1. Start `konsole`
 1. run `screen`
 1. type: http://bugs.kde.org
 1. Hover with the mouse, over the URL such that it is underlined
 1. press Ctrl-a + c
 1. The underline is still there

Old bug, which (unforunately) hasn't been fixed. :(

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. But don't worry! This issue is being tracked by the KDE developers at: http://bugs.kde.org/show_bug.cgi?id=154550
Once fixed in KDE, it will be included in Kubuntu once the KDE version the fix is in in reaches Kubuntu.

Thanks!

still present

[Bram Avontuur (bram-avontuur)]

Still present exactly as described in the initial 2007 report. When using screen this is highly annoying.

[George-t (george-t)]

I am experiencing the same but in 14.04 LTS

My specific experience with this bug on a tri-head two video card system (both nvidia running open source driver) is as follows:

When konsole is on primary video card display the problem does not present itself.

When konsole is on secondary video card display the problem is absolute and the screen does not refresh until the mouse moves on the screen or a key is pressed.

When the konsole spans Primary->Secondary monitors, the portion of the window on the primary display updates immediately whereas the portion of the window on the secondary display only updates as described above (on mouse event etc).

I hope this helps someone smarter than I figure out the issue!
