When tooltips are fading in and out, the animation flickers and isn't smooth. This seems to happen for all the tooltips. It is most visible in systemsettings' default overview tooltips. Hovering and unhovering an item doesn't show a smoothly blending animation, but a flickering between shown and hidden for the time the animation runs. This leads to a jarring user experience. My naive interpretation is that either or both of the following might be wrong: - Some effect doesn't correctly identify the item as tooltip and animates them while it shouldn't - Another effect gets in the way, and manipulates the opacity as well, one or the other wins, more or less randomly for every frame -> opacity jumps up and down, it flickers. Reproducible: Always Steps to Reproduce: 1. Open systemsettings 2. Hover mouse over an item 3. Wait for tooltip to show, move away or to another item Actual Results: Tooltips shows a flickery animation while appearing Expected Results: Tooltip smoothly fades in and out
the problem is "Save intermediate rendering results" in the blur effect. I'm quite sure we already have a bug report for this problem.

Yes, appears to be a duplicate of https://bugs.kde.org/show_bug.cgi?id=307112 I can confirm disabling the blur effect resolves this issue.
