They link dynamically, and I tried to replace Qt libraries for Viber,
but it just crashes
somewhere inside their binary.

We're living in real world, and most companies aren't interested in
supporting Linux well enough.
Viber version wasn't updated for quite a while, and I don't believe
that they will release an update anytime soon.

Anyway, fixing every application instead of fixing it at the lower
level doesn't sound reasonable.
