Description David Chmelik 2022-06-24 12:48:43 UTC

SUMMARY
Usually no longer works to group programs on text taskbar.  One is forced to select every program, then it may work initially, but if taskbar space frees up but then you open more programs to need grouping again (such as increases from one to two task rows) grouped ones never seem to regroup unless you undo & redo.

STEPS TO REPRODUCE
1. Revert to normal text taskbar.
2. Group programs.
3. Free up space then open more programs to need group.

OBSERVED RESULT
Usually can't group programs.

EXPECTED RESULT
Group programs and return option to group /all/ without having to do dozens separately.

> 2. Group programs.
Can you be specific about how you are grouping your programs?

A screen recording might help so we don't have to go back and forth a bunch.

> Can you be specific about how you are grouping your programs?

There's apparently only one way left with text taskbar: right-button select the program -> more -> allow this program to be grouped.

It's nothing complicated enough to do that (and the only way to do this) and can't do recordings anyway.

Comment 3 Nate Graham 2022-06-27 16:53:12 UTC

I asked because I can't reproduce the issue when I toggle grouping like that, so a screen recording if you reproducing the issue would be helpful.

You should be able to use the Peek, SimpleScreenRecorder, or OBS apps to record the screen. There's no reason why onw of them should't work, especially on X11.

non-grouping

This screen video shows Chrome/Chromium was meant to group, didn't, but only did after reset (Firefox does same.)  I realize these aren't KDE programs but usually don't use more than one window with KDE programs... I can test one if depends more on who makes it.  At time of this video, about 1% to 2% of system CPU resources were used, 10GB RAM free, no audible HDD activity (where /home/user/.kde is) but main KDE itself is on SSD.

The video was too large and KDEnlive is counter-intuitive with outdated documentation, so I couldn't select part of it but had to end up using VLC and FFMPEG... video making/editing is extremely difficult and I'd rather not do it.

Comment 5 Nate Graham 2022-07-05 15:52:09 UTC

Interesting. Thanks for the video. It's clearer now.

FWIW shouldn't be necessary to use kdenlive and ffmpeg to make a screen recording. Peek, SimpleScreenRecorder, and OBS make it simple, and the filesizes are small.

Part of it is also if a program is grouped, and you open another, the grouped one ungroups again.

Comment 7 David Chmelik 2022-07-18 14:16:45 UTC

Actually on any sort of taskbar update/action they ungroup.
