Hello,

I am currently moderating the list until we find a way to avoid spam 
more efficiently. I am not yet up-to-speed with the new list software we 
use, sorry. This is an issue for people who write to the list without 
being subscriber. I have whitelisted you now, so that you can post freely.

Note that you can start lyx with '-userdir foo' to get the same effect. 
Configure should be run automatically in this new directory.

This is weird, I do not know where to start to debug this. We have 
issues with Wayland (that are fixed in git now), but xorg is supposed to 
work.

It is only the LyX work area that is not updated or the whole window 
(toolbar, menus...)?
