Yesterday (3 May) I wrote:
I want to disable the setting “Use printer metrics for document
formatting” in Libre Office Writer (Libre Office 6.0.3.2 on Ubuntu
18.04). When I deselect it it is automatically selected again every
time I open a document, whether a new document or an existing one.
It occurred to me that this might be buried in the advanced features
(Tools > Options > LibreOffice > Advanced > Open Expert Configuration).
I found two references to compatibility here, under
org.openoffice.Office.Compatibility > AllFileFormats >
org.openoffice.Office.Compatibility:FormattingOptions['user']
and also
org.openoffice.Office.Compatibility:FormattingOptions['default']
In both places UsePrinterMetrics is set to “false”. I quit the program,
and when I open it again the setting under Tools > Options> LibreOffice
Writer Compatibility has changed back to “true.”
