I have also tested with Kvantum and same issue, not only with Lightly. I have tested both in Fedora 37 and Ubuntu 22.10, both with KDE 5.26 This report was done with Fedora Bug with Ubuntu: #463162 In both bugs I was using this customization guide (only appearance settings, including Latte-Dock and ULauncher with both Lightly and Kvantum) https://www.youtube.com/watch?v=y4yPm9s3KVg
I've been able to hunt down the issue to replicate it 100% of the time Here is the video: https://i.imgur.com/biOTdkC.mp4 What I've done after clean install: 1. Clean install Fedora 37 2. Installed both Anydesk and Google Chrome 3. Followed this tutorial https://www.youtube.com/watch?v=y4yPm9s3KVg for appearance settings (both Kvantum and Lightly option do the bug, so they are not the root cause) 4. And then do what I show in the video. It happens 100% of the time.
Sorry, I forgot to explain what I do in the video exactly: 1. Anydesk open 2. I open Google Chrome full screen 3. Close Google Chrome 4. Minimize Anydesk 5. KWin crashes.
Can you try to get debug symbols for libkwin.so and get a new backtrace. It'll help narrow this down quicker.
(In reply to David Edmundson from comment #4) > Can you try to get debug symbols for libkwin.so and get a new backtrace. > It'll help narrow this down quicker. I'm not sure how to accomplish this. I had Kwin right in the distro, not compiled from sources I need to compile https://github.com/KDE/kwin from sources with some sort of flags or something?
You can do "sudo dnf in kwin-debuginfo kwin-common-debuginfo kwin-libs-debuginfo kwin-wayland-debuginfo"

Ok, sorry for the time passed, but I had issues with my laptop drivers and had to go back to Windows for a while Now I have reinstalled everything and KWin bug seems to be there. Going back to the last point I left with Nicholas Fella > # sudo dnf install kwin-debuginfo kwin-common-debuginfo kwin-libs-debuginfo kwin-wayland-debuginfo This is the error I find. Those debug packages doesn't seem to exist in dnf Error: Unable to find a match: kwin-debuginfo kwin-common-debuginfo kwin-libs-debuginfo kwin-wayland-debuginfo Anyway, from what I see in Fedora 37, which I'm using there is debunginfod which is mentioned in this guide https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Fedora But I'm still not sure how to specifically debug kwin related crashes with such tool apart from the backtraces I've offered in this thread.
