Note that I use latte-dock simply as application launcher, no widgets.
Only 'shortcuts' to applications, e.g. Dolphin, Firefox, Blender, Krita, Trash, etc

Thanks.

1. try latte git version to confirm this.
2. use default layout
3. and of course use https://userbase.kde.org/LatteDock/HowToReportCrashes in order to provide a detailed crash and informative bug report

Are you wasting my time?
Can you not reproduce?

See following bug report (confirmed)
https://bugs.kde.org/show_bug.cgi?id=451028

I can not reproduce because I lack the needed hardware. Policy of Latte bug tracker is to accept only:
[1]. crash reports that either I can reproduce and based on that the crash points to Latte code
[2]. crash reports that pin point exactly which Latte part code is responsible.

If a crash report does not provide [1] or [2] then is flagged as NEEDSINFO and is closed automatically after 30 days. This policy was chosen for the simple reason that Latte can not be blamed in any case for graphics drivers issues/upstream plasma libraries issues/upstream kde frameworks issues/upstream qt issues/upstream kwin compositor issues etc...

So if you think I am wasting your time, no problem for me but this is how things works in latte bug tracker. As there is no latte pin point somehow in the mentioned crash reports I will forward this bug tracker to your mentioned found upstream bug.

If you think that I am wasting your time then

I understand policies, but policies cannot hinder workflow with unreasonable request from end-users.
Otherwise the end result is that bugs will stay in the application unresolved, even if reported.
kde bugtracker happily accepted my bug report and confirmed, latter-dock bug tracker did not.

This is wasting people time (yours and mine) with unreasonable request.
Maybe its time to review some of the policies.

best of luck
