Slackware 13.37, tested on 2 different PC;
affected: mousepad and tcl/tk applications

Hello

I am using mousepad and tcl/tk application to view
text files with long lines. Some times ago i found
that some characters (part of line) in long lines
disappear. The problem is shown on a very small video.

I wasn't found any real solution.
Any help are welcome.

Best regards

Piotr

Mousepad has a "wordwrap" option.

"wordwrap" option is disabled.

enabling it should fix your problem

This is not a solution. I need this option to be disabled.

Can you perhaps explain why? It would fix your problem

Because wrapped text is completely unreadable in this case.

You should see the missing characters if you use the scroll-bars.

Use smaller characters and wider window.

I don't understand what you mean...

500-1000 characters per line... in wider window?
This is not a solution.

First time the problem appear in Slackware 13.0.
Earlier versions works fine (since 2004).

Is it just Mousepad and "tcl/tk application", or have you observed this in other editors (like kwrite and gvim)?

What is going on?

Can you post some sample data that will allow us to reproduce the problem?

I type this

dfg dsfhdg hfg hfg h fdg hdfghdfhfd ghgfh fgh df ghdfghdfgh dfghdfgh fgh fg h fgh dfg hdfghfghfghdfhdgfh dfgh dfg hdfghfghfgh fgh dfg h dfgh fg hdf gh fgh fg hfd gh gf hfg h fgh gf hf gh fd h dfgh gf hfd gh dfg hfdhfghfgh fgh fg

random characters in KWrite and only first 22 chars was visible (see bellow)

dfg dsfhdg hfg hfg h fd

rest of the line disappear (is invisible).

I type this in gvim

gfhjdghfghfgh fghjkdhgkfjhgsdjkghd kjghf sgkjfhgkjfghkjfghfhgdkjg hdfkjghgkjhgkjfhgkj ghfkjghfkg jhfdgkjhgkjfghkjghfkjghfdkj ghfdkgjfdhgkjfhgfkjghdfk gjhfdgkjdfhgfkjghfkj ghfdkgjhfdgkjfhdgj kdfhgkfdhgkjdfhgk jdfhgkjdfghk jfghkfjhgkfjghls gkjs hgksh kjhgksjf hkjfshg kjs ksj glsk lkjdklj

and expand the window (to see most of chars in one line) and many
characters disappear (effect exists only on some widths).

kwrite and kate have a built-in keyboard shortcut for dynamic word-wrapping: F10. Press the F10 key and the text will soft-wrap. Or look for the same option in the View menu.
