Created attachment 85654 [details] Screenshot showing the problem This is tricky to reproduce, but what i do is: * Open a popup menu that is very long (in my case right click on a kmail folder, but i could reproduce it also in short konversation menu that apears on right click over the chat view) * Move the mouse like crazy up and down over the menu Eventually you end up with two rows highlighted, the one where your mouse is resting and one where it had been previously but failed to unhighlight
This could be a duplicate of bug 307372, depending on whether the same code is used to handle the hover animations in QMenu and QMenuBar.
This still happens with the Qt 5 version, and is fairly easy to reproduce with menu items above a separator.
Fixed my own bug, one year later, reviews plz? https://git.reviewboard.kde.org/r/123807/
Git commit b680714d4845aef3ad44c39b6e48e029f000a62d by Albert Astals Cid. Committed on 20/05/2015 at 13:02. Pushed by aacid into branch 'Plasma/5.3'. Fix popup menu items getting stray highlighted Make sure we "finish" the animation before stopping it. Moved the mouse like crazy over the "Help" menu of konsole and can't get it to be wrong anymore.
