Description Akarsh Simha 2007-12-23 20:32:49 UTC

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.

Comment 4 Kurt Hindenburg 2009-01-04 01:40:06 UTC

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

still present

Comment 8 George 2014-06-20 17:49:12 UTC

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!
