xdg-desktop-portal-wlr: Screencast not working with latest chromium (85.0.4183.102)

I’ve recently noticed that the screen casting is not working anymore with the current latest chromium (85.0.4183.102) on arch.

▶ yay -Q | grep 'sway\|wlr\|pipewire'
bemenu-wlroots 0.4.0-1
libpipewire02 0.2.7-1
pipewire 0.3.10-1
sway 1:1.5-1
swaybg 1.0-4
swayidle 1.6-1
swaylock 1.5-1
wlr-randr 0.1.0-1
wlroots 0.11.0-1
xdg-desktop-portal-wlr 0.1.0-4

With the same versions I did manage to get it working with an older chromium version (84.0.4147.135-1) and I gathered the logs from this command (/usr/lib/xdg-desktop-portal -r & /usr/lib/xdg-desktop-portal-wlr -l DEBUG) with both of them.

With 85.0.4183.102

I was unable to share my screen in Chromium lately, as well. However, my issue seems to have been fixed in xdg-desktop-portal version 1.8.0. I might have hit the bug described here. However, for another user, the problem persists.

Yup, I’m experiencing the same as of this morning. Looking into it.
