Skia drivers and the Skia implementation in LibreOffice is being actively
developed. While Vulkan vector hardware acceleration may be problematic with
older hardware/driver pairs, the Skia raster rendering should be reliable and
an improvement over GDI based rendering.  If Vulkan works with your GPU/driver
combination, great use it!  If it has problems, be sure to update drivers and
retest. If still has issues--disable it and use Skia raster rendering.

Only if both modes of Skia rendering have trouble--disable and use the default
GDI rendering, just expect that it will be slower.

The backing window for the two icons are redrawn dynamically depending on the
color you've picked. They're not static. That they are black when you are using
Skia Vulkan rendering is a glitch, but if that is the only glitch for an
otherwise well supported GPU (like your Intel HD Grapchics 630) then keep using
it (but do update the driver as Intel provides--the Vulkan and general Skia lib
support is constantly being improved).  But if you are more comfortable (or if
the GPU/driver pairing is given "Deny list" handling) just work in Skia
software raster mode.
