I solve the problem by uncheking skia
Comment 2 Luboš Luňák 2020-09-15 09:44:45 UTC
Please enable temporarily Skia again and provide the info from the About dialog, and also contents of <cachedir>/skia.log (where on Windows the <cachedir> should be AppData\Roaming\LibreOffice\4\cache).

Does the problem exist also if you enable Skia but force it to use software rendering (about dialog showing Skia/Raster)?
How much RAM does your computer and your graphic card have?
Does the problem exist even if you open a new empty Writer document?
