These 3 should do it:

* acaebed014 - (HEAD -> emacs-26) ; * src/ftfont.c (ftfont_spec_pattern): Fix 
whitespace. <Eli Zaretskii>
* 97d61f878e - Port FC_COLOR change to older fontconfig <Paul Eggert>
* f21fa142ac - Ignore color fonts when using Xft <Robert Pluim>

Closing the bug report, thanks for testing.
