First Wayland failure

[GreyGeek]

I was working with Kate and had 1,073 documents in the FileSystem list I selected another document I wanted to open and selected Kate at the app to open it.
Here is what followed:

This plugin supports grabbing the mouse only for popup windows
qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x555f30279de0 ) which does not match the current topmost grabbing popup, Qt

ting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that
child popups close before parents

But......what actually happened?

I don't understand this part:

had 1,073 documents in the FileSystem list

What list?
What application? I assume something running under Wine?

Is this Kubuntu 22.04, and its older Qt, or neon and its current Qt?
Kwin in Plasma 5.24 isn't necessarily the best choice for a Wayland compositor. I don't recommend 22.04 for more than general Wayland testing.
Plasma 5.27 is much improved etc et al ad nauseum

I use Kate to scan a group of files in a folder looking for a word or phrase. Kate is opened with three panels: the list of files in the left panel, the results of the word or phrase search in the right bottom panel, with each line containing the file name and the line in which the word or phrase appears. When I click on a line on the right bottom panel the actual document opens in the top right panel where I can read and capture text.

The activity was interrupted by the error msg I displayed in my first post.
EDIT:
Here is a screen capture of the activity:

When I scroll in the bottom right panel and click on line from a file that file is displayed in the upper right panel. All 1,073 files are selected in the left panel. The error msg appeared when Kate crashed while doing this. However, the problem has not reoccurred.
