Theme parsing error: gtk.css:20:1: '/*' in comment blockI tried searching for all gtk.css files in /usr/ and found maybe 20 or so. I don't know which ones are triggering the warning. Another site says the warning arises because there's a non-break space in line 20 of gtk.css. Trouble is, "which one?"
From system settings > theme, I show this setup:
Window borders: Mint-X
Mouse pointer: DMZ-White
The error has arisen when I run the following commands from the terminal:
gnome-terminal, file-roller,brave-browser, xed, etc. Some of the responses are in different colors.
Which gtk.css file(s) do I edit to get rid of this warning?
