Font smoothing issue on Windows 7, green fringes on vertical edges with dark mode

Summary:

When dark UI theme selected, white font becomes green tone on dark background. It looks like bad font smoothing. Selected menu items on light UI theme also looks not well.

I got this issue on 1.0 and 1.0.2 versions of Inkscape. Unslable development version of GIMP also has this issue: https://gitlab.gnome.org/GNOME/gimp/-/issues/6005 . But stable version of GIMP looks good. Same way, I don't see this in old version of Inkscape (0.92.5).

Steps to reproduce:

  • open Inkscape
  • change UI theme to HighContrastInverse
  • look at fonts tone of UI text: menus etc.

What happened?

Text drawing greenish.

What should have happened?

Font rendering should be more accurate.

Issue more visible when using light font on dark background. Inkscape_1.0.2_Dark_Theme

Black font on light background looks not bad. But white font on blue background (selected menu items) looks worse. Inkscape_1.0.2_Light_Theme

Inkscape v0.92.5 has only Win32 UI theme (no dark themes), so can't test it good, but selected menu items probably looks better then in 1.0+ verions. Inkscape_0.92.5
