I can confirm this in the Debian Installer as well (spotted early April
but only debugged right now).
Getting a little back in time and comparing what unstable used to be at
20200401T154401Z and at 20200405T084040Z, I'm seeing these changes in
the list of udebs used to build the netboot-gtk image:
-libcrypt1-udeb_1%3a4.4.15-1_amd64.udeb
+libcrypt1-udeb_1%3a4.4.16-1_amd64.udeb
-libdrm2-udeb_2.4.100-4_amd64.udeb
+libdrm2-udeb_2.4.101-1_amd64.udeb
-libpango1.0-udeb_1.42.4-8_amd64.udeb
+libpango1.0-udeb_1.44.7-3_amd64.udeb
-libudev1-udeb_245.2-1_amd64.udeb
+libudev1-udeb_245.4-2_amd64.udeb
-udev-udeb_245.2-1_amd64.udeb
+udev-udeb_245.4-2_amd64.udeb
Compare attached 1/2 screenshots to see the regression.
To make sure the pango update was responsible, I deb-reversion'ed its
udeb (taking the old udeb, faking a higher version so that it would be
preferred to the new udeb), and rebuilt the installer with unstable
from 20200405T084040Z, and I can confirm the regression disappears
(see 2+revert screenshot).
Cheers,
