Linux: Import Bookmarks Dialog not showing text

[rome-legacy]

I'm on Ubuntu Linux 24.04, installed Raindrop Desktop app as snap (latest/stable 5.6.76)

When i try to import Bookmarks by opening the import dialog, the text is not readable

i had the same with a confirmation dialog too (don't remember which)

is a font missing?

will gladly provide more information, if you need.

kind regards
