Screencast

KDE neon 5.21 ships with a ridiculous number of completely irrelevant Noto fonts (hieroglyphic, cuneiform etc.). In KDE 5.18 I was able to remove them. In 5.21, I get an error that every single one of them does not actually exist.

The problem is that this list of exotic fonts clutters the font selector in applications (LibreOffice etc.), and makes it a pain in the ass to select the font I want.

Why are fonts in all sorts of non-Latin alphabets installed to begin with, when I selected US English in the installer? Are they some variants of Noto that can't be separated from the useful ones? Bundling them together seems like a patch for a very corner case in which a user needs Egyptian Hieroglyphs and Mayan Numerals, rather than a solution, but I guess that's an issue for a different component.

The issue here is that I *was* able to delete these fonts in 5.18, and now I'm not. Trying to disable them results in the same error. I'm stuck with that long list of crap on a daily basis, in all applications that have a font selector :-/

Combined with bug 433166, this makes it a net worse experience to have upgraded from 5.18.5.

Eek. Can confirm.

Findings so far:

It does work in 5.20

It fails FontInst::findFontReal
Even though the initial list comes from FontInst

After a lot of bisecting, it seems this was caused by 567d49f55c2cd4a7dab5e5c70c688b3f3ff42203
