Comment 4 rafrey 2020-01-08 22:11:32 UTC

I reinstall old from timeshift ok. Reboot and update && upgrade all, for exemple plasma-desktop/bionic 4:5.17.5-0xneon+18.04+bionic+build68 amd64 [actualizable desde: 4:5.17.4-0xneon+18.04+bionic+build67]
and the same problem.
kwin: symbol lookup error: /usr/lib/x86_64-linux-gnu/libkwin.so.5: undefined symbol: _ZN12KDecoration215DecoratedClient25hasApplicationMenuChangedEb
systemsettings window decorations crashes, etc.

It appears to me like you have a problem with your installation. What version of KDecoration do you have installed?

Hi Vlad.

Comment 7 rafrey 2020-01-13 07:06:21 UTC

With Kubuntu in another hard disc, same problems.
I reinstall KdeNeon and don't touch the system boot (Grub2 and my own Grub theme, discarded) and ¡¡ very well !! all is ok .I've been without problems for several days.
Thanks.Greetings

Comment 8 Vlad Zahorodnii 2020-01-13 09:43:58 UTC

Okay, changing the status of the bug report to NOT A BUG.
