Screenshot with wrongly placed tooltip

Cannot reproduce with a full git master session.

Do you see this issue in any other apps, or just System Settings?

I can reproduce it in KDE neon "Unstable Edition/Unstable branches" with updates from today, see attached screenshot.

tooltip problem in KDE neon

I saw a similar (but not quite the same) problem with drkonqi, see bug #438643.

Ah *those* tooltips.

Same bug affects Kicker and popups of applets in system tray, see bug 443843.

kwin titlebar tooltip appears on wrong display, in correct horizontal position

I noticed something like this, but slightly different to other reports. I have an external DisplayPort monitor above my laptop screen, and I keep my task bar and most windows on the upper display. Today I noticed that the tooltips for the titlebar icons of every window on the upper screen appear at the top of the laptop display below, see attachment. You can see the the tooltip is in the correct horizontal position but on the wrong display, as if it's constrained to fit on the laptop display.

Application tooltips, applet tooltips, etc. all appear in the correct place on the correct display; titlebar icon tooltips of windows on the laptop (lower) display appear in the correct place. I've never noticed this before, and in this session I changed my Colors theme to fix bug 449587; I suspect the glitch will go away after I restart. I adjusted monitor positions slightly and changed my Colors theme again and the glitch remained. Nothing appears in journalctl at the time I hover over a titlebar icon, though I see a bunch of

wayland: Fix mispositioned decoration tooltips

QPlatformScreen::virtualSiblings() must return a list of screens on the
virtual desktop, otherwise QToolTip will use
QGuiApplication::primaryScreen() instead of looking up the screen where
the decoration tooltip must be shown using QDesktopWidget::screenNumber().

I just switched to Wayland from X11 and encountered this issue on Plasma 5.25.2

In that case, it's one of these two Qt bugs:

Screen layout

For reference, this is my screen layout. Not sure why the bug was marked as resolved when it's clearly not resolved. Just because the bug exists in mainstream doesn't mean the users do not suffer with this project. I personally think it's a very bad practice to close the issue in the actual project which is suffering. Upstream may not even care about the issue.

Nate Graham can we reopen in case other users suffer from this issue?

Qt bug is fixed in Qt 6.4 but the tooltips of apps built against Qt 6 like Strawberry music player are still misplaced on Wayland.
