Theme issues when starting i3 session with startx instead of lightdm. (lemmy.ml)

I'm trying to migrate from lightdm to just using startx to start my i3 session.

First I had issues with kdeconnect working which were fixed by replacing exec i3 with exec dbus-launch --exit-with-session i3 in the xinitrc.

Now even though the apps works it is not following the system theme, I checked qt5ct and it is telling me that QT_QPA_PLATFORMTHEME is not set to qt5ct.

But I do have export QT_QPA_PLATFORMTHEME=qt5ct on my ~/.profile it seems the file is not being read but I have no idea on how to fix it.

i3 is actually exporting the enviroment variables when I set them in its config file, however for some reason qt5ct and all the qt apps refuse to use it, running printenv confirms that it is there.

However I found the issue, it seems to be an issue with my zsh shell, because I just created ~/.zshenv and added my enviroment variables there instead of on ~/.profile and now it works like it should kek. I didn't have to do this before when using lightdm so no idea what exactly changed though.

It is likely that the qt enviroment variable needs to be exported very early and that is why doing it from i3 doesn't work but from the shell it does.
