screenshot of the problem

GIMP 2.9.8 commit 18794a6ba2

Turning text antialiasing on/off has a clear impact, but toggling hinting between none/slight/medium/full makes no difference whatsoever.
Comment 1 Michael Schumacher 2018-01-19 09:00:19 UTC 
That colored outline hints at a general anti-aliasing misconfiguration on your system - the subpixel hinting is not supposed to bleed into applications.

Text everywhere else looks fine
Comment 3 BugsBunny 2018-01-19 09:11:11 UTC 
Reproduced this problem using all fonts on my system, including Verdana, Arial, Noto Sans, DeJa Vu, etc.
Comment 4 Michael Schumacher 2018-01-26 12:37:17 UTC 
So was there any change once you got rid of infinality in bug 792669?
Comment 5 BugsBunny 2018-01-27 10:11:42 UTC 
Removing fontconfig-infinality-20130404 improved the situation. Now there is a difference between hinting "none" and hinting anything-else. However, there is no difference between slight/medium/full, only between none and any of those. I tried many fonts, including the ones listed above.
Comment 6 Michael Schumacher 2018-01-29 09:10:02 UTC 
With Arial at a size of 12px in a default 300 ppi image, I get a difference between None, Slight and Medium - the most noticeable change from Slight to Medium is that the glyph height slightly increases.
