comparison rendering of Help -> About current 7.0.0 alpha0+ master

The attached image shows clips of the Help -> About dialog from a Windows 10
Ent 64-bit with nVidia K2000 GPU (26.21.14.4128)

panels, left to right, are showing rendering by

Default GDI
OpenGL
Skia/Vulkan
Skia/raster

I know quality is subjective, but the Default GDI rendering seems crispest. The
OpenGL DWRITE grayscale antialaising is acceptable.  But for both Vulkan
renderings, the antialaising seems too heavy--almost smeared--note the O o 0
and ( ), as well as the W and V glyphs.
