swaybar blurry fonts with pango 1.44

[rumpelsepp]

sway --version
sway version 1.2 (Aug 29 2019, Arch Linux)

Since pango 1.44 swaybar looks blurry, see screenshots below. Remember to max. zoom the screenshots, otherwise they look blurry because the browser scales them.

I have these output settings:

Swaybar on the non scaled output looks like this (DP-7):

Swaybar on the scaled output like this (eDP-1):

Swayber seems to render scaled on DP-7. At least the dpi settings look wrong to me.

Probably: harfbuzz/harfbuzz#1892 (comment)

It may not completely fix the issue, but #4555 should have some impact
