Bug 458007

Thanks for the bug report! Unfortunately we need a single bug report per issue; don't report multiple problems in a single one. Let's focus on the panel issue.

Can you clarify what you mean by they "slide off the window bar on every launch"? When you launch an app by clicking on its icon, the icon disappears? Or something else?

Let's keep the discussion here, in public.

Can you attach a screen recording that shows the issue happening?

It seems like there's some confusion here.

This is the KDE bug tracker; it's used for tracking bugs in KDE software. It's not a user support system. Support requests should be directed to your distro or the KDE forum. If there's a bug report here, it means there is a possible bug in KDE software. You might want to read through https://community.kde.org/Get_Involved/Issue_Reporting.

My job is to triage these reports so that they can become actionable for developers (or so I can fix them myself, if they're easy). To do that, I have to be able to reproduce the issue myself. Right now I can't do that because it's not clear to me what exactly is going on because you're using nonstandard terminology. Which is fine; you can't be expected to know what we call everything! But as a result, I don't know if you're talking about a Plasma panel or a Latte Dock panel; I don't know if the icons you're referring to are pinned Task Manager apps, or standalone launcher icons; I don't know if you're using a traditional Task Manager or an Icons-Only Task manager, and so on. The fastest way for me to get answers to these questions is if you attach a screen recording so I can see for myself what's happening.

Email is no good because, again, this isn't a user support system. Bug reports are discussed in the open, in public. So comments, files and attachments need to be here, in this bug report.

Can you please attach the requested screen recording? Thanks!

If it's too large to fit, you can also upload it somewhere else and paste a link to it here.

I can't, but I will contact KDE's sysadmins who can clean it up.

The sensitive information has now been cleaned from this bug.

I'd recommend making replies within Bugzilla itself going forward rather than through your email client as that will give you greater control over what is published.

Thank you verry much....   :-)

Can you provide the requested screen recording now? It would be much appreciated. :)

KDE start, with window bar permanently displayed. Icons move toward the center of the screen

Thank you for your help  :-)

Got it, I see now. So the panel changes your desktop dimensions when it appears, so that the icons on the desktop move around. This is currently the intended design, but we could potentially change it to reserve some space where the panel *will* appear, before it's appeared.

Do you have the splash screen disabled? Or does the splash screen appear, and then it disappears, and then after that, the panel appears?

No, the start screen is not disabled, but when I auto-hide the panel, the icons slide down, including under the panel, and stay where they are. The error occurs on the panel that is normally always visible and pushes the icons further and further up, away from the panel. If the panel is on the right or left, keep going towards the center. What I also think is important, I work with activities. That means I never have the same desktop, but change it from time to time.

> No, the start screen is not disabled, but when I auto-hide the panel, the icons slide down, including under the panel, and stay where they are. 
Yep that's expected.

I think the resolution here is to reserve space on the desktop for a non-auto-hide panel even before it's loaded on boot, so that the desktop icons don't shift around once it does load.

is this resolution so unusual?

yes, it works, thank you

Not fixed yet; icons still move when the panel appears because space is not reserved for them.

In my case (https://bugs.kde.org/show_bug.cgi?id=468733) the problem is the vertical panel moves the icons many columns randomly.
Original icons: https://bugs.kde.org/attachment.cgi?id=158244
Moved icons: https://bugs.kde.org/attachment.cgi?id=158245

Is it the same problem?

Same root cause of the desktop resolution changing during the panel appearance animation, which triggers icon-position-changing code to run inappropriately.

KDE Plasma 5.27.5

*** Bug 492003 has been marked as a duplicate of this bug. ***

(A response for https://bugs.kde.org/show_bug.cgi?id=492003#c11, but also worth commenting it here.)

I don't know if the fact of icon scrambling can be considered a missing "feature". As far as I know (but I could be wrong), KDE defaults to the taskbar always being visible ("non-auto-hide").

Due to the fact that this causes problems for those who have several icons on the desktop (like my case here), having to fix the icons almost every reboot or using them in a completely messy way is a very bad thing. In my opinion, it is a bug of very high importance, and not something that "will be fixed eventually". I ask the devs to consider changing the importance of this bug from "minor" to "major".

For example, when comparing KDE to GNOME, by default, GNOME does not allow icons on the desktop, so having something in KDE that does not work properly is certainly sad.

I've been suffering from this bug since Plasma version 5. I started using Plasma with Fedora Linux 39.

This definitely doesn't meet the qualifications for major (no workaround, or the workaround is painful and difficult), but the fact that it affects the default configuration means that we can at least raise it to normal.

positioner: Load icon positions on perStripe changes

Previously we did not load the icon positions before updating on
perStripe change. This meant that we never "reclaimed" any lost space,
for example when user has a panel on left side of the icons which
causes them to move on initial loading.

We should just load the positions every time perStripe changes to make
sure the icons reclaim their space if needed.

This adds a flag parameter to loadAndApplyPositionsConfig, which can be used to
skip loading perStripe from config when it changes.
