Recently the default theme seems to have switched from “Anysphere Dark”, which looks fine, to “Cursor Dark Anysphere” (I’m not sure exactly when this happened, I’m on 0.46.2).
“Cursor Dark Anysphere” looks very strange to me in the files panel, see attached screenshot. The files look greyed-out and broken. I’ve changed the theme but I was very confused by this! “Anysphere Dark” looks fine here, as do all other dark themes that I’m aware of.
