Bug ID: 396096
Summary: /usr/bin/kwin_wayland asserts: Scene::windowClosed:
assert(m_windows.contains(c));
Product: kwin
Version: 5.12.5
Platform: Debian testing
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: bernha...@mailbox.org
Target Milestone: ---
Just tried a plasma wayland session and found following when closing a window.
Might be related to using non default theme (changed it last year because of
a Qt bug).
What looks suspicious is that KWin::ShellClient::destroyClient is twice in the
callstack for the same object.
If there is anything else I can provide, the core file is still there and
all needed debug packages installed.
(Not sure about the component selected for this bug report.)
Core was generated by `/usr/bin/kwin_wayland --xwayland --libinput
--exit-with-session=/usr/lib/x86_64'.
Program terminated with signal SIGABRT, Aborted.
