SUMMARY STEPS TO REPRODUCE 1. Go to the Application Launcher 2. hover the cursor on some app icons that have long comments (which have ellipsis dots) OBSERVED RESULT some tips are stick there till you move the cursor off and some start flickering EXPECTED RESULT all the tip should stick until you move the cursor off them ADDITIONAL INFORMATION X11 with Intel Graphics this is a little hard to reproduce for me. sometimes it works correct after i wait for a while
I can't reproduce this on my system (git master, AMD GPU, Wayland). Can you attach a screen recording showing it happening? Thanks!
Created attachment 185987 [details] show how to reproduce
Thanks. Does the issue still happen in a new clean user account created on the same computer, with no customizations applied?
Sorry, I have not test that，i just found this issue accidentally and i found that the Kcal application just has higher possibility for this issue to happen🙃
I will provide more information if i find ,just need some time...🙃
Never mind, I can reproduce it. I have to position the pointer in a location where the tooltip will overlap when it appears. It's never supposed to overlap, so there's some positioning bug somewhere.

I think I figured out the cause of this and https://bugs.kde.org/show_bug.cgi?id=511875 (and possibly other tooltip positioning issues in QML apps). Here in Kirigami's SelectableLabel tooltip's x and y properties are overwritten: https://invent.kde.org/frameworks/kirigami/-/blob/e2ef3baddb292cb8b796854e879f1b028cfa1ea8/src/controls/SelectableLabel.qml#L325 This is **bad** because ToolTip accessed via attached property is global. This makes original x and y bindings in qqc2-desktop-style's ToolTip to break everywhere where attached ToolTip is used. Not sure what the correct fix should be (Binding?).
Or maybe just instantiating separate ToolTip as suggested in Qt docs: https://doc.qt.io/qt-6/qml-qtquick-controls-tooltip.html#custom-tool-tips
