<pre>What you show is screen tearing, extending horizontally across entire lines of
text as the document canvas is redrawn with scrolling (by mouse, touch pad, or
cursor arrows).
It has nothing to do with font metrics and the rendering of the fonts. Likewise
it probably has nothing to do with your mouse hardware & drivers (the scroll
size is not read from your mouse settings, rather from LO program settings).
Skia rendering is enabled by default with the Windows builds. You must
explicitly disable it to revert to "default" GDI based rendering by CPU (with
optional CPU controlled Hardware Acceleration).
We need to know if the tearing continues when you eliminate Skia and switch to
GDI rendering.
Also, we need to know your graphics hardware, so before disabling Skia--with
Vulkan rendering enabled--copy the contents of the Skia.log from
%APPDATA%\LibreOFfice\4\cache\skia.log and if present the opengl_device.log</pre>
