[Desktop] Bug since Plasma 6 - Yakuake and KRunner have graphical glitches/inconsistencies with top panels

[Schwarzer Kater]

Yesterday I had finally (!) tried to officially report this to the KDE Bugtracking System, but no joy until today: My account is no longer recognized (it has not been used for several years, though).
Perhaps I’m misremembering the password, but resetting it doesn’t work either - nor does creating a completely new account…
So I’ve given up on it for now and am writing this post instead.


The Bug:
Since KDE Plasma 6.0.x / Yakuake >= 24.x there have been graphical glitches (X11) or inconsistencies (Wayland) in combination with Plasma top panels.


The graphical glitches in X11 can look two ways - it always concerns about half a line of text at the top when the panel is floating:






The graphical inconsistencies in Wayland concern the attaching to the top panel (Yakuake should always attach directly to the panel IMHO):




The only case where Yakuake behaves in Plasma 6 as it should IMHO is with a non-floating top panel both in X11 and Wayland:







In Plasma 5 (X11) / Yakuake 23.08.5 this has not been the case (the final Kubuntu LTS version with Plasma 5 is 24.04).
Yakuake behaves as it should IMHO and always attaches directly to the top panel - no matter if floating or not:







However, it is not just Kubuntu 26.04 LTS / Yakuake 23.08.5 that is affected: This also occurs e.g. in openSUSE Tumbleweed with KDE Plasma 6 / Yakuake 26.04.1 or Arch with KDE Plasma 6 / Yakuake 26.04.2…

Yakuake is by far the program I use most frequently on every one of my installations with KDE Plasma - so I see this several dozens of times a day.
Perhaps someone who cares (and has the ability to do something about it) will read this.



Addition: For KRunner see post # 7.

Dear Mr CW,

thank you very much for digging that up and stepping in.

Unfortunately this bug report only covers half of it:
The more annoying bug where in X11 about half a line of text gets cut off at the top or is slapped onto the floating top panel - and which has also existed for quite some time - is not mentioned there at all.

Although X11 is not officially supported by the Kubuntu developers in 26.04 LTS anymore, KDE still officially supports X11 in Plasma 6.6.x and will continue to do so until Plasma 6.7.x.
And I am very certain that several of my customers and friends will continue using X11 (and therefore Plasma 6.6.x or 6.7.x) much longer than the official support from Kubuntu or KDE lasts (myself included).

Would you be so kind as to also mention the graphical glitches in X11 regarding Yakuake and floating top panels and/or to post a link to this thread?
I would greatly appreciate that - thank you again.

Yours sincerely,
SK

There is, IIRC, another bug report on the opposite.

Dear Mr CW,

Where do you get the W from, or am I a cut-rate TV channel?

Cheers, Mr Wizard (no, seriously - take a look at e.g. your passport… ).

Your second link covers the "older effect" in X11, unfortunately not the current one(s) with a floating panel. But it could be the right place nonetheless - I will try again to reactivate my bugtracker log-in when I am back home the coming weekend/next week…
Thanks again.

You mean my bugzilla comment . I am not one to hide my real name anywhere, but trying to get me paranoid is gonna make me lose sleep!!

By the way: a similar bug also exists with KRunner and floating top panels in Plasma 6 - this time it is quite the same both in X11 and Wayland:





One can see it a bit better with a light panel:




With a non-floating top panel KRunner's positioning looks OK in Plasma 6 - like it looks with Yakuake.

So I'm guessing your CW (Mr. CW) is 'Claydoh Wizard'?

[die.boer]

i briefly read through all the detailed bugs mentioned ...
i don't experience any of it ,something must be wrong with my system

I ain't no wizard, but the cee-dub is my initials. Are my initials? Argh.

In any case, you know my name but anyone can see it in the bug report comment.
Though to be perfectly honest, that is not my actual first name.
