There is a delay on hover to display the items. I feel it is best to make it instant. No delay on mouse hover in Kickoff. When it is not, it gives the impression that there could be something wrong with the system.
I've had this on my system for a while.
I did find myself switching to "computer" as I moved up to select an entry.
Could definitely be reduced though.
FWIW it's currently 250ms

Yeah, people erroneously see this as a performance problem: https://www.reddit.com/r/linux/comments/7v8frc/kde_this_week_in_usability_productivity_part_4/dtrjvn2/
Regardless of the merits of the feature itself, we might consider changing it just to eliminate that potential source of confusion and frustration. We don't want to make ourselves look bad here.

Implement a triangle filter for mouse events on the Kickoff tabbar
D11848 started out with the aim to remove the delay on Kickoff tab
switching, but this proved contentious because it can cause user
frustration over accidental tab switching when moving from the tab
bar to the list view at angle, grazing another tab.
This patch implements a triangle filter to get the best of both
worlds. When the mouse motion vector is within the triangle from
the vector starting coordinate pair to the relevant tab bar
corners, the original 250ms delay remains in use. When the vector
is outside the triangle, tabs are switched immediately - improving
even over the 50ms delay proposed in D11848.
Care is taken so that tab switching is always immediate when the
tab bar is freshly entered, e.g. moving from the panel to Kickoff.
As a small advantage this removes a MouseArea item from each tab

18.08.0 is the version of KDE Applications, not KDE Plasma. I wouldn't expect you to see this in action because it's been fixed in Plasma 5.14.0, which hasn't been released yet. See the "Version Fixed In:" field.
