Hi Andre,
I applied the patch to xfdesktop-4.13.2 on my Gentoo Linux. After a brief
testing I have indeed no new core dumps in my /var/dumps/, great. I realized
that if I use Fn+F1 to use only my external HDMI display and to turn off the
laptop's internal LCD, after lid open my laptop has again enabled LCD screen
and using the size of the external HDMI display (1920x1200 instead of its own
max 1366x768). I do not recall seeing this before. Could this be caused by your
patch?
$ dmesg
[ 746.362842] [7102]: Lid closed.
[ 754.655963] [7102]: Lid opened.

Maybe some checksum could be logged too so one could better discern when
the event triggered and to better match it so .xsession-errors file
contents? In the below log the messages around "Negative content width
-1" were supposedly caused by libreoffice which remembers position o the
window from a last execution and placed the window on my laptop indeed
somewhere above the left upper corner. I assume that is because it
remembered position from my 1920x1200 external HDMI screen while at the
moment I was using laptop's internal 1366x768 screen. As there is no
"Move window" place around the window luckily the only way to get to the
menu of the window is to use "Maximize window" from the Xfce panel.
Anyway, the logged events you added in the patch should bear a timestamp
(see below).
