Created attachment 134865 [details] Screenshot of the konsole icon missing despite it being open. SUMMARY The last icon in the icon-only task manager will disapear in certain situations. It seems to happen only when there is a spacer somewhere in the panel and the first pinned application is not active. STEPS TO REPRODUCE 1. Add a spacer to the panel 2. Have exactly three icons in the manager with the first one not active. 3. The last icon will not show, but there will be a spcace for it. 4. I can reproduce with different applications/icons and in different size configurations. I've attached a screenshot with the missing icon and my system information. OBSERVED RESULT Konsole icon missing EXPECTED RESULT Konsole icon visible SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.9.16-1-Manjaro KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
I've been unable to replicate this issue. I've got Menu Spacer IconTaskList Systemtraystuff in that order to replicate close to yours but when I open konsole it shows up.
Also cannot reproduce with that setup. Odd.
Created attachment 134946 [details] Video of icon disapearing.
Does adjusting the height make a difference? I added a video of the icon disappearing and reappearing as I adjusted the height.
Created attachment 135006 [details] flexible size on
Created attachment 135007 [details] flexible size off
I can reproduce this. Note when flexible size is ON and the panels height isn't 20-32 or 56, icons disappear or rather they move to the 2nd row which isn't visible. A quick workaround it to configure the icon-only manager to have ONLY 1 row.

I just started seeing this with my last update. It seems to effect Dolphin and VLC regardless of where they are in the order.

I can consistently reproduce this with IOTM configured to show only one row. As long as the taskbar fills its available horizontal space, the next application I open doesn't show its icon. But if I open a second one, both icons are shown.
Just reproduced that with a horizontal panel. I can't get it to happen with a vertical panel though.
Could someone test https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/989 fixes this bug?
