Comment 12 for bug 1976178

I have the same problem.

I've installed Pinta v2.1.1 on macOS Monterey (12.6) using Homebrew :

% brew info pinta | gawk -F"[/ ]" '/usr/{print $(NF-1)}'
2.1.1
% locale | grep LANG
LANG="fr_FR.UTF-8"
%

When I click on the /Applications/Pinta.app icon, it launches Pinta in english instead of french.

But when I type this from a ZSH Shell, Pinta starts in French (as expected)

% open -a pinta
%
