WowAce

Hello, I have the problem that the fonts appeared only with a delay. I thought it was ElvUI, but I reinstalled WoW today and had no problem with the fonts at the beginning with Elvui. When I installed SharedMedia, the problem was back. I once added a picture: https://imgur.com/55eKhBQ
You then have to open and close the window several times. Then at some point all fonts will appear.

Maybe there will be an update? For Shadowlands too? Or has the addon been canceled? :)

SharedMedia just provides a mapping between font names and their corresponding file paths. It isn't directly involved in the creation of the dropdown you see (besides providing the data). So there isn't anything I can do to help you with this.

I've seen it happen to others though so I guess Blizzard changed something regarding font loading. The fonts that seem to be initially visible in your screenshot are base game fonts and the one already in use, so it seems the others aren't loaded, yet, by the time the game tries to render the dropdown.
