Text antialiasing not working as expected

GIMP version: 2.10.8

Operating System: Antergos 19.02 (Clean installation, tested in 2 different computers)

Package: gimp (I also tried gimp-git and the problem remains)

Description of the bug

Gimp feature false colors on text antialiasing (See example).

Reproduction steps:

Use the text tool to create white colored text over a white background.
This will make obvious that the text was aliased in yellow/blue tones (Instead of grey tones, as expected).
If you disable antialiasing, the weird colors dissapear.

…

Expected result: The text is aliased with correct, gray tones (As in the 1º example).

Actual result: The text is aliased in extremely obvious yellow/blue tones (As in the 2º example).

Using gimp 2.10.8 from Flatpak fixes the problem.

Apparently this bug is very old.
