Bug 421697

You need to find more information, it works just fine in my Latte git version

Send also your Latte layout file in case something is broken in it.

Layout File

My current layout file as if this moment.

I am able to reproduce this with a new default layout. I'm also not seeing anything weird when I toggle the setting when launching Latte Dock from the terminal with the debug flag.

Recording of tasks disappearing.

your layout works fine in my system. How do you install Latte ?

I clone it from here and run the install script: https://phabricator.kde.org/source/latte-dock/

Try the following:

1. Close Latte
2. Remove everything in:
   - /usr/share/plasma/plasmoids/org.kde.latte.plasmoid
   - /usr/share/plasma/plasmoids/org.kde.latte.containment
3. Reinstall Latte
4. Run it

and checkout if you still have the same issue

The issue still remains after removing those directories and reinstalling Latte Dock.

so strange, I wonder what can be different in your system and that does not occur in mine.

We can try the following:

1. Move your left panel at the bottom
2. Close Latte
3. Start Latte with: latte-dock -d --layouter
4. Metrics will appear for each applet, layout etc...
5. Can you make a screenshot? do you notice something in the metrics that it is strange?

or maybe better run Latte with:

latte-dock -d --layouter --graphcs

it will provide also visual debugging for each applet

latte-dock -d --layouter --graphics

On my openSUSE Tumbleweed desktop where I'm running the latest git version from trmdi's OBS repo I'm not having this issue, in fact it's working perfectly.

On both of my Fedora laptops I went through and made sure all the necessary devel packages were installed, and I'm not getting any warning that anything is missing when I'm running the install script.

Another update: Tried building from the script on Kubuntu 20.04, all required dev packages installed, same issue occurs when enabling scrolling.

try to remove everything in : /usr/lib64/qt5/qml/org/kde/latte/
and reinstall Latte, does it still occur?

waiting feedback

Purged that directory and reinstalled using the install script, did not work, issue still occurring on both Fedora 32 and Kubuntu 20.04.

I am out of ideas

Some more testing around and I found that playing with the min/max length of the panel will impact whether or not the Latte Tasks disappears. 

1. If the min and max value match then it disappears. 
2. If I keep opening applications it will actually proceed to ignore the max and just keep growing the panel instead of shrinking. 
3. If the min is set to 100% or it's set to panel mode using justified then Latte Tasks disappears.

from all three I can not replicate any in my system. We need a concrete way to reproduce in my system:

1. Add a new Dock from Dock Settings
2. Send here in for new Dock step by step how you can replicate the issue

So far I run into this issue when I pull from git and run the install script on Kubuntu 20.04 and Fedora 32 KDE. For the hell of it I decided to do the same on my openSUSE Tumbleweed desktop and it works just fine.


Is there something out of date on Kubuntu 20.04 or Fedora 32 that would be causing any build issues? I've got all the dependencies listed on Phabricator so I it's not throwing any complaints that I'm missing anything that the documentation requires of me.

probably qt 5.13. but my system is Tumbleweed so I can not reproduce. Such issues are difficult to fix. Either I have to install the problematic distro and check out what is going on OR another developer that is using them will search the issue.

these should be fixed with current latest git version.
