Some fonts may require additional configuration to display properly, so usually manual installation should be avoided.
Please run (and post the result here) fc-match sans and fc-match serif to check fontconfig picks wrong italic font.
If that's the case, try to remove the TTF files you've installed via the font manager you're using, then install the fonts via the package manager - it should configures fonts properly.
The SCHEMA:PATH part seems slightly wrong (singular vs. plural). Try:
bash
schema=org.gnome.settings-daemon.plugins.media-keys.custom-keybinding
path=/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/
gsettings get "${schema}:${path}" binding
gsettings get "${schema}:${path}" command
gsettings get "${schema}:${path}" name
Firefox has "permissions.default.image" (link) option that disables image loading, but this Wikipage is very old so I'm not sure whether it works properly in current FIrefox.
As already suggested, take a look at i3 Window Manager's docs: https://i3wm.org/docs/userguide.html because Sway (works on Wayland) is a port of i3 (works on X11).
I think it doesn't work. I skimmed Lemmy source code (search scrape_text_for_mentions if you're interested)
and found this issue so I'm almost sure the mention in the post body
doesn't work, but haven't tested, so I used the word may. Sorry for your confusion.
Without proxying or other means, images are automatically loaded. A
user may post tracking images to collect IP addresses or to harras a
specific user. It's quite different from manually opening the external
sites (that aren't autotmatically loaded) to read stories.
Thanks for writing the summary for the current image-proxying related
issues. I prefer the "proxying images route" for better privacy, but
its drawbacks sounds worse.
If Lemmy has a user-customizable setting like "Don't load external
media automatically" (including images, videos, etc.), I'm happy with
the "passing through external images" route.
AFAIK contents aren't shared automatically between servers. See https://join-lemmy.org/docs/administration/federation_getting_started.html
