To solve the bug reported here the solution seems to be commenting, not just adding a certain line in a file - as explained here and here.That is - to make that bug disappear in Xfce, a certain line has to be added. But as that is not enough, the suggested solution is to comment that very line. I have the impression that the solution works. Is that placebo?How come a line is necessary, but also has to be commented, that is - deactivated?
In which way is a commented line active in a program file?
command line;files;command
They are commenting a line in a configuration file.  Really, it would be working around a bug of some sort.  In other words, having the line in the configuration file activates the broken code.  Commenting it out in the configuration file leaves the broken code dormant, and things work again.It only fixes it from the user perspective.  The user thinks the bug is fixed because their program works again.  But really, it is just a workaround.
