Yakuake opens in the center of a screen instead from top (like before),
i see that changing windows behaviour>advanced>window placement affects how Yakuake opens the window - however I believe it shouldn’t ? Yakuake should open always from the top ?
but even changing that windows placement setting, doesn’t make Yakuake to behave like before (like in Plasma 6.3?)
Have you logged out or restarted plasmashell since seeing this, or closed down Yakauke and restarted it?
I have seen this happen with Yakuake and/or desktop notifications before, usually after a Plasma related update or version upgrade, and haven’t done so, or after a plasmashell crash.
If a logout/reboot hasn’t fixed it, and you are fully updated, it may be a bug in this PPA. You can check if it is a system-wide issue or something more specific to your desktop configs by creating a new user account and seeing if it happens there as well.
