3. Press enter multiple times in rapid succession

OBSERVED RESULT
Multiple instances open and no opening window animation is played

Can reproduce the multiple instance issue. It doesn't happen in KRunner itself or Kickoff, only Overview.

I can't reproduce the lack of opening animation issue though. It's possible your opening animation is shorter than Overview's close animation.

Either way, let's track that in another bug report, if you don't manage to trace it down to a configuration issue.

After some further testing it seems to be tied to the closing animation of Overview. Overview still takes in input during the closing animation, causing the multiple instances thing and, when searching for an unopen window, all the other open windows in that virtual desktop are hidden and when closing Overview brings the windows back abruptly which causes the opening window animation thing. Both problems are more noticeable when you turn the animation speed down.
