I’m seeing the steam blackscreen issue, but the workaround doesn’t seem to be working for me?

Ah, I investigated Steam shows black screen only since last update but this is a different issue, as the entire UI is black, not just the webview.
This is also affecting some games, such as Loop Hero and Factorio.
EDIT:
Rebooting twice while changing nothing else seemed to fix it?
