When I start entering text in Calc that is the same as previously entered text in the same column, the balance of the text is automatically entered but in a dark (black) highlight that obscures the automatically entered text. How can I change the highlight to something that allows the text to be viewed?
It is a graphical aberration when your graphics card doesn’t fully support Skia. In Tools > Options > LibreOffice > View tick the box Force Skia software rendering. Allow LibreOffice to restart and the aberration will have gone. Cheers, Al
