KDE Plasma: Apps do not minimise to task bar/panel
As stated when you minimize an app it doesn't appear on the control/task panel.
Any idea how to correct this?

Re: KDE Plasma: Apps do not minimise to task bar/panel
Many issues are upstream ones, so I would check https://bugs.kde.org/ and/or https://discuss.kde.org/ ..
Perhaps journal messages could shed some light for you.
In some cases removing and readding a plasma widget can fix corruption.

Good idea, not a great solution, but deleting the panel and generating a default new panel as replacement, along
with some customization did the job.
OTOH, KDE ( or maybe QT6 ) "upgrade" has indeed produced a lot of new issues. I can throw in no printer queue in
the System Tray, and Screen Locking doesn't turn off monitor after a set interval... unless you deliberately activate
it with CTRL-ALT-"L" ... then it works... and other glitches all intro'd by the Plasma 5/6 transition.

Re: KDE Plasma: Apps do not minimise to task bar/panel
I have literally none of these issues.
Can you elaborate on your setup? Maybe post a screenshot or so? Which task manager are you using? What output do you get from
qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.dumpCurrentLayoutJS #Needs qt5-tools, qt6-tools and qdbus6 if you're allergic to Qt5
glxinfo -B

Re: KDE Plasma: Apps do not minimise to task bar/panel
Looks saneish, X11 or wayland? are you using a custom plasma theme that might have suboptimal inactive/background colors and the entry actually existing but plain not being visible due to color scheme or so? Might need more context

LOL sane is a good place to start.
This is X-11. plasma theme is oxygen but style/color are custom... there is no unaccounted for "spaces" that might hint at hidden icons/etc due to color.
