If you're using Arch Linux or anything based on it (or other rolling update distributions) and you've recently run updates that included freetype2, you might unfortunately notice that Steam is now quite broken.
When loading any part of the Steam client that depends on web views, it will just give you a rather unhelpful black screen. This is obviously a big problem and makes it all quite unusable. So what can you do? Well, if you're comfortable with your package managing you could downgrade freetype2 back to version 2.10.4 but that can then end up breaking future updates that depend on the newer version. Valve are hot on the issue though and they've already put up a fresh Steam Beta with a fix.
Valve contractor Timothee Besset commented on GitHub to say it's "Today's beta update comes with a fairly significant change to the way we setup the runtime environment for the web views. Please test that this addresses the issue on all affected distributions!". So if you're seeing the black-screen issues, try out the latest Steam Beta. Doing so is easy by just loading up Steam settings and then look for the red boxed area shown below:
Arch Linux does at times have issues like this, because updates are constantly rolling so issues end up being found much quicker - which also means by the time other distributions upgrade (like Ubuntu every 6 months) the issues are likely solved by then.
