Application: kdeconnectd (1.4.0)

Qt Version: 5.14.2
Frameworks Version: 5.75.0
Operating System: Linux 5.10.12-100.fc32.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 32 (Thirty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
Log out from session.  My KDE widgets always get garbled after a suspend/resume (Nvidia).  Logging out/in restores widgets but often sddm crashes or leaves me at a black screen forcing me to reboot.

- Custom settings of the application:
KDE connect seems to have caused this one.  I also use Compiz and Emerald decorations.  None of this happens on my Dell XPS laptop with Intel integrated GPU.

-- Backtrace:
Application: KDE Connect Daemon (kdeconnectd), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
