Hi, I just update my Libreoffice
Build ID: 1:6.4.5-0ubuntu0.18.04.1
CPU threads: 4; OS: Linux 4.15; UI render: default; VCL: gtk3;
Locale: en-US (en_US.UTF-8); UI-Language: en-US
My Laptop is Thinkpad Yoga370
Opening any local file ( empty or not ) will have 5s loading delay ( the application window is open but all grey ).
Opening the application only without loading file works normally
Previously doesn’t not have any problem.
