When opening Yakuake, a task bar entry is shown Reproducible: Always Steps to Reproduce: 1. Set Configure -> Window -> Duration to "500 ms" 2. Open Yakuake via hotkey 3. See that there will be a "Yakuake" entry in the task bar for 500 ms Actual Results: Task bar entry Expected Results: No task bar entry
This is likely a combo of a behavior change in Qt 5 that allows setting NetWM state only after QWidget::show() instead of in advance, because Qt's show() will clobber state. The 500ms delay probably comes from the fact that you're on the legacy xShape codepath and there's a bug causing the prop setting code to only run when the animation completes. As a workaround, try getting on the preferred kwin assisted codepath (GL compositing needs to be on and the checkbox in Yakuake).

Make the xshape codepath apply window props as early as the kwin path. M +2 -2 app/mainwindow.cpp http://commits.kde.org/yakuake/36f4cb9376487602d9cb33814292318455dae749
Just upgraded to Kubuntu 16.10, which ships Yakuake 3.0.2-1. I'm still seeing this behavior. I can help debugging.
Taskbar entry may or may not appear, it seems to be completely random.
Oh, and when it appears, it stays there till i hide yakuake.
I also experience this issue on openSUSE Tumbleweed with Yakuake 3.0.2, Plasma 5.8.2, Frameworks 5.27.0 and Qt 5.7.0. It's the same symptom here as Antonio Orefice has reported.
I also experience this issue on Kubuntu 17.04 plasmashell 5.10.3 yakuake 3.0.4 Qt 5.7.1 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 6.3.0 20170124) on "xcb" plasma-framework: 5.35.0a-0ubuntu1~ubuntu17.04~ppa1
Still present on KDE Neon User edition with plasma 5.10.4. Will this bug be solved?
Confirming this bug without hiding of entry from task bar - mostly appears - sometimes not in Yakuake 3.0.4+ Qt Version: 5.9.1 Frameworks Version: 5.36.0 Operating System: Linux 4.9.40-1-MANJARO x86_64 Distribution: "Netrunner Rolling"
