When setting “export SAL_USE VCLPLUGIN=kf5” e.g. in ~/.bashrc, Calc is ignoring this environmental variable when opening an existing .ods file and instead uses gtk3 or X11 (when libreoffice-gtk3 is uninstalled) !
More strangely a new .ods file will be opened/created with kf5, but after saving it, Calc opens it with gtk3 (or X11)! Also LibreOfficeWriter opens all files with kf5 correctly!
Is this a known bug?
How can I force the kf5 plugin for all .ods files in LibreOfficeCalc?
Thanks!
B.t.w. I’m preferring kf5 because GTK and X11 plugins are causing terrible (cursor, input line) lags when moving / browsing through complex sheets!
