nm-connection-editor do not apply gtk3 theme

Hi all, I'm working on a Pixelbook Go with a fresh Arch Linux installation. I'm using wayland + labwc and the theme I chosed is Arc-BLACKEST. The machine is working really good and I really like how it looks I'm having only a small "problem", I installed the network manager applet but when I open the nm-connection-editor it's window theme do no follow the one I set in the .config/gtk-3.0/settings.ini (Arc-BLACKEST), I do not understand what I'm doing wrong. The theme has been unpacked and copied to .themes folder and is correctly detected by lxappearance. I installed pcmanfm as file manager and it should use gtk2 that has been configured by lxappearanceI to use Arc-BLACKEST and it works fine. What I can do to inspect what is happening ? I do not know what else I can try, any help will be really appreciated.

Re: nm-connection-editor do not apply gtk3 theme

Unsure what the exact cause is (do other themes work, like Adwaita-dark?) but you can start to debug it like so:

$ sudo pacman -Sy; sudo pacman -S strace
$ strace -f -o save.me -e trace=file -s 1024 /usr/bin/nm-connection-editor

This uses strace to (f)ollow forked threads/processes, (o) saves output to a file, (e) only traces file access, and (s) sets the string length to 1024 (since we're tracing file access, we want a longer/more verbose output than the default for seeing full filenames).  Then use a quick grep to find where it's opening files in your home directory to get started:

$ grep home save.me | less

A "correct" (working) system should show (a) it opening the INI file, then (b) it looking for that named theme until it's found, etc. so on mine using Adwaita-dark it looks like....

63978 access("/home/TE/.config/gtk-3.0/settings.ini", F_OK) = 0
63978 openat(AT_FDCWD, "/home/TE/.config/gtk-3.0/settings.ini", O_RDONLY|O_CLOEXEC) = 8
...
63978 access("/home/TE/.local/share/themes/Adwaita-dark/gtk-3.0/gtk.css", F_OK) = -1 ENOENT (No such file or directory)
...
63978 access("/home/TE/.themes/Adwaita-dark/gtk-3.0/gtk.css", F_OK) = -1 ENOENT (No such file or directory)
...

...the spirit being on your system, you should see something similar except it'll find "/home/A4EVA/.themes/Arc-BLACKEST/gtk-3.0/gtk.css" or whatnot with a success message (in strace lingo the line will end in "= 0" which means "opened the file without error, about to read it!" more or less). A quick look at the Arc-BLACKEST Github repo shows this theme hasn't been updated in 5 years so... _shrug_  Good luck!
