Can reproduce.

For me, the drop-down animation happen only once on the first opening.
All subsequent opening animations are the growing one.

Fix Slide effect on Wayland

Qt Wayland windows have their internal Wayland surface destroyed when they're
hidden, and re-created when they're shown. Since `KWindowEffects::slideWindow()`
requires the Wayland surface, it doesn't work when called after `hide()` and
before `show()`. The solution is simply to call it directly after `show()`; window
opening animations are asynchronous so the effect is applied to the window as
it's opening.

This bug persists on neon unstable.

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.24.80
KDE Frameworks Version: 5.93.0
Qt Version: 5.15.3
Graphics Platform: Wayland

Its working for me now, which means that we solved the original bug of it not working for anyone, and now we have a new bug that only affects some people. Let's get a new bug report for that.

*** Bug 454444 has been marked as a duplicate of this bug. ***

I'm the reporter of Bug #454444. I confirm now that this bug is solved. On the latest 5.99 KDE Frameworks, and 22.08.2 (forgive me if I'm mistaken with version numbers). Yakuake now properly slides in from the top on Wayland as on X11 - as was always expected.

I'm really, really happy about this fix, in-fact was the only "wayland showstopper" for me for two years now (on Fedora). Thanks a lot, I can't appreciate this enough!

Wonderful news!

I was eager to know what commit/change actually fixed it here. Specifically, I'm running Yakuake v22.08.1, Plasma v5.25.0, KDE Frameworks v5.99.0 & Qt v5.15.6 on Fedora KDE with updates installed upto 22-Oct-2022. As far as I inspected, this fix was incorporated months ago => https://invent.kde.org/utilities/yakuake/commit/7a319db432c13343b6da2203171b2cc5e70c8f1c on Yakuake v22.04. I went through 21.12->22.08, every versions of Plasma, KDE Frameworks, Qt versions even the last Fedora (since Nvidia added GBM) since then, and I tested yakuake every time I did an update. It's only in this specific versions combination (G22.08.1+P5.25.0+F5.99.0+Q5.15.6) that resolved it - although Manjaro, as I stated earlier, was immune to this even before Yakuake v21.12 on wayland.

I'm sorry but drop-down when i touch the top screen edge is still not working for me on Wayland.

Is there something to do ? Any configuration or workaround that would allow me to use this nice feature ?

yes, drop-down on edge on Wayland doesn't work for me either. But it's nothing I cared much about, as I use F12 key anyway.  :)
