@Oliver, *

Just wrote this up on an issue, does this get you started...

LibreOffice Tools -> Options -> View there are four config choices for rendering:

(1) "Use Skia for all rendering" -- this is default on Win builds and uses Skia calls to Vulkan vector based rendering

(2) "Force Skia software rendering" -- this still uses Skia libs but with calls for raster framing, reduced and simplified GPU load

(3) "Use hardware acceleration" -- with Skia disabled (both unchecked) and LibreOffice restart uses CPU and OS gdi rendering with calls to the GPU for HA (still GPU driver dependent). 

(4) unchecked hardware acceleration -- with Skia disabled (both unchecked) uses only CPU for gdi rendering.  Noticeably slower. 

Anti-aliasing is enabled by default and the Skia libs do it well, but disabling can lighten load on CPU when gdi HA is off, tradeoff in appearance of text and draw objects rendered to display.
