Description aditsu 2011-04-14 15:33:19 UTC

Version:           4.6 (using KDE 4.6.2) 
OS:                Linux

Refer to the video at http://www.youtube.com/watch?v=fHaKkDKY2ZI for an example of a dolphin window "dancing" - it apparently recalculates the layout back and forth. I also noticed the same problem (more often) in the notification window when copying files.

Reproducible: Sometimes

Comment 1 Peter Penz 2011-04-15 14:16:57 UTC

Can you reproduce this issue in Dolphin with a small sample directory when using the details-view? I'm not sure about the notification window but at least in case of the details-view it might be an issue in Dolphin.

Comment 2 aditsu 2011-04-15 14:29:14 UTC

Ah, that was easier than I thought: http://www.youtube.com/watch?v=7j-mcYrbunc
New folder, new text file, and there it is.

Comment 3 Peter Penz 2011-04-15 16:08:36 UTC

Thanks for the video but I cannot reproduce the issue. I've used the same columns, the same directory + content, tried to use the same window width etc.

Could you please give us more information:
- Does this occur only with the details view?
- Does the issue depend on the width of the window?
- Does the issue depend on the number of activated columns?
- Which widget style are you using? Oxygen?

What I could reproduce is that when decreasing the size slowly that the Date-column and Type-column might get clipped although there is enough space. I guess when solving this issue your "dancing" issue will be solved too, but it would be great if I could reproduce the "dancing" too ;-)

Anyhow: Assigned to Dolphin, will investigate...

Comment 4 Peter Penz 2011-04-15 16:10:04 UTC

Ha: Could reproduce it now :-) (1 minute later) The width must have a specific size so that the horizontal slider might get shown.

Git commit 8c6cdd0780404a3edfe2ce6045c86d2375d5942f by Peter Penz.

Details view: Fix jumping column-widths

If the view has a width where a horizontal scrollbar is required to
show all columns, an endless loop might get triggered that results in a
periodic jumping of the column-widths.

Comment 6 aditsu 2011-04-16 05:07:07 UTC

Thanks, I also recorded 2 clips for the notification window, one with a large file and another one with a lot of small files: http://www.youtube.com/watch?v=ZVVfJkXAcho and http://www.youtube.com/watch?v=qF2vZYFCWKk
Is that a different issue? Or did your commit also fix it?

Comment 7 Peter Penz 2011-04-16 14:21:27 UTC

@Aditsu: Could you please open a new bug-report for the notification window? The notification window is part of plasma, I guess there should be a sub-category for this. Thanks!
