Huh? Go to any Walmart and you’ll see loads of physical copies. Switch 2 is even confirmed to use them.

IIRC it technically does but needs a certain flag set on build. So either users need to build it themselves or distro maintainers need to do it on their end https://github.com/flameshot-org/flameshot/issues/2848

I’m not aware that Steam has ever allowed copying screenshots to clipboard. Is this new? Either way, might be related to Wayland if you’re running it. Flameshot acts the same way.
