Arch Linux 64 bit. KDE Plasma 5. LO + language pack (russian). All is up to date.
If started from command line without localization, everything look good:
LC_ALL=C libreoffice
Fresh and Still versions are the same. Googling was no effect.
Hello, Try turning off OpenGL. From menu select Tools->Options then under LibreOffice->View insure Use OpenGL for all rendering is not checked. Select OK. Close all open LO documents. Then see if problem solved.
There is no such option. But after relogin in test account there is and unchecked, trying to check it resulted in no able to start after closing (only reset all with --safe-mode turned things back).
If this is a distro version you may want to report to them. Have no problems in various Ubuntu/Debian systems using v5.x from LO.
