Hi Tomáš,
I think `\rm` would be the matching switch for `\ss` (roman and sans-serif).

I can perceive a difference in “Evince” at 6564.6% zoom (and continuous
mode) compiling your original sample (no display or view glitch).
It disappears when I replace your first command with:
\definefontfamily
[mainface]
[ss]
[Latin Modern Sans]
I wonder whether by not defining properly the font family
(https://www.pragma-ade.com/general/qrcs/setup-en.pdf#search=definefontfamily
shows that the these first three brackets are required) may influence
how the font has its features enabled or not (kerning among them).
Sorry, it’s only a(n educated?) guess. Just in case it may help,
Pablo
