I mean to just move the cursor over the categories in the launcher to see the
applications. I attached a video showing it.
The CPU usage of plasmashell is high during it, and if you do any minor task in
the background, like watching a video, it gets much slower, up to two seconds
till the applications show.
This doesn't happen when Discover is installed. Or it's at least much much
better.

I am not sure what you mean with hovering over a category.
if (mime.isEmpty()) {
if (!mimeType.startsWith(QLatin1String("x-scheme-handler/"))) { //
don't warn for unknown scheme handler mimetypes
qCWarning(SERVICES) << "KApplicationTrader: mimeType" << mimeType
<< "not found";
return lst; // empty
}
mime = mimeType;
}
There is code in KServie to avoid lots of warnings, but in case the schema
handler is known to QMimeDatabase, but (for whatever reason) not to KService
internally, we will emit a warning later on.
