Are you getting warning messages like the following when you launch a LibreOffice app from command-line? Although a LibreOffice app might start and display its user interface as expected even with those warnings, you may experience glitches while actually using the app (ex. fail to update control layout when its main window is resized).
luca@x410dev:~$ libreoffice --writer
javaldx: Could not find a Java Runtime Environment!
Please ensure that a JVM and the package libreoffice-java-common
If it is already installed then try removing ~/.config/libreoffice/4/user/config/javasettings_Linux_*.xml
Warning: failed to read path from javaldx
Are you still getting the same warning messages even after installing
libreoffice-java-common and removing
sudo apt install libreoffice-java-common
In such case, try installing
default-jre package. 'javaldx: Could not find a Java Runtime Environment!' might be pointing to the right culprit, 'jre (Java Runtime Environment)'...
sudo apt install default-jre
