Bug ID: 279753
Summary: x11-wm/plasma6-kwin: crashes Xwayland under Plasma
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: Individual Port(s)
Assignee: kde@FreeBSD.org
Reporter: jbeich@FreeBSD.org
Assignee: kde@FreeBSD.org
Flags: maintainer-feedback?(kde@FreeBSD.org)
Plasma 5 isn't affected. Tested inside jail nested under a wlroots-based
compositor. Without Plasma "kwin_wayland --xwayland" doesn't seem to start
Xwayland process (unlike plasma5-kwin) but /var/log/messages is silent.
