Linux slight hinting breaks 'u'

[CapSel]

I narrowed down problem with rendering letter u in word router to hinting setting.

Here I used bold version of the font with all ligatures (except ss02) enabled and hinting set to "slight":

Here same font configuration except hinting is disabled:

Of course hinting disabled looks "ok" on main screen but not on all.

I downloaded the font today from system packages - it's 1.101 OTF.
