Bug#881891: xwayland: FatalError() when new monitor is added (not always reproced)
Package: xwayland
Version: 2:1.19.5-1
Severity: important
Tags: upstream
Dear maintainers and developers,
My laptop OS is Debian Buster. The xwayland crashed when one new monitor was
added. This cannot be always triggered when the new monitor is added. After I
install the debugging symbols of xwayland, the crash is from one FatalError.
Attach stack trace:
