Version-Release number of selected component (if applicable):
kamoso from Fedora kamoso-18.03.80-4.fc31 repo  and kamoso updated to kamoso-20.04.1-2.fc31.x86_64 built on corp

I'm testing it here:
https://copr.fedorainfracloud.org/coprs/sergiomb/builds_for_Stable_Releases/package/kamoso/ with https://src.fedoraproject.org/rpms/kamoso/pull-request/1

it could be related to #422847, can you test a build with my patch?

https://invent.kde.org/edevito/kamoso/-/commit/cd88623d21f571a94322dfb9c6c27996d8550188

I have builded a fedora package with this patch, you can find it on my corp repository: https://copr.fedorainfracloud.org/coprs/scorpionit/kamoso/

kamoso from copr:copr.fedorainfracloud.org:scorpionit:kamoso  doesn't fix the issue
Thanks for your efforts

comparing yours output with mine the only difference is that I don't have this row:

"file:///usr/lib64/qt5/qml/org/kde/kirigami.2/private/globaltoolbar/PageRowGlobalToolBarUI.qml:49:13: Unable to assign [undefined] to bool"

at this point IMO this is a kf5-kirigrami2 bug that should be fixed in 5.70 release (version I currently have on my pc)

if I am right, this should be fixed by this update: https://bodhi.fedoraproject.org/updates/FEDORA-2020-00e6a09bb1

I have updated but now icon of settings on the left has disappeared .

The setting button shouldn't be on the left, but inside the right sidebar.

I runned a clean install of f31 inside a virtual machine and I noted that with kf5 5.68 installed there is an "hamburger menu icon" on the left that don't do nothing, imo this icon shouldn't be there.

All kamoso options are inside the "Configure Kamoso" page

and https://userbase.kde.org/images.userbase/8/87/Kamoso-Settings.png doesn't exist any more ?

Kamoso hasn't looked like that for a long time. What's the bug here?

So now kamoso doesn't let just adjust camera setting ? , so where I do that ? neither we have plugins ? 

If yes , sorry this is not a bug anymore , kamoso-20.04.2 seems is working as expect .

Thank you for your time

Yep, looks like those features were removed at some point. :( I wonder why.
