Bug ID: 427382
Summary: kwin crashes under wayland
Product: kwin
Version: 5.19.5
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: multi-screen
Assignee: kwin-bugs-n...@kde.org
Reporter: peter.ste...@stptech.at
Target Milestone: ---
SUMMARY
Fresh install of KDEneon-User (Download Oct. 27, 2020) works fine with X11 but
crashes frequently under wayland. The applications still are working. Killall
and restart of kwin resolves for some time.
STEPS TO REPRODUCE
1. just wait, it happens frequently sometimes after minutes, sometime after zwo
hours.
OBSERVED RESULT
/var/log/syslog shows the following logs (last line shows the timestamp
indicated also by the clock in the menu bar:
Oct 6 12:20:08 surface-pro plasmashell[359283]: qt.qpa.wayland: Wayland does
not support QWindow::requestActivate()
Oct 6 12:20:12 surface-pro plasmashell[359283]:
file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:285:5:
QML Connections: Implicitly defined onFoo properties in Connections are
deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }
Oct 6 12:21:29 surface-pro plasmashell[359283]: message repeated 2 times: [
file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:285:5:
QML Connections: Implicitly defined onFoo properties in Connections are
deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }]
I am documenting the crashes and the outputs of the syslog and the above line
repeats frequently. Also the fact, that it coincidents with the stop of the
menu-bar watch points to these lines.
I could not find any special combination with a specific application and/or
action.
Similar behaviour came up with Manjaro and tumbleweed installation (but I do
not have logs of these) when I was searching for a stable installation. KDEneon
seems to be the most stable one however.
Willing to make further experiments in order to resolve this issue.
