I have an old .xcf file that contains several text layers. When I created the file, I edited and changed the text multiple times without issue.
Now, several months later, on a new OS and new version of GIMP, when I select the text layer, it lets me edit it without asking for confirmation, however the font shows up in red as "Standard Symbols". As soon as I make any change, e.g. type in one extra letter, the whole text layer changes to look completely different.
I don't remember if I used a specific font back then that I no longer have installed. Is this the problem here? If so, can I find out which font the text is supposed to use?
