I have a Gtkmm desktop app that requires root access. It worked fine on 18.04 using Lxqt-sudo but after upgrading to 20.0.4, it takes ~30 seconds to open only the first time after booting. In addition, it will skip the splash screen that's supposed to show for 3 seconds. However, every subsequent launch will show the splash screen and everything works fine, until the system is rebooted again. Logs for the minute this occurs:

What I've tried:
Simply modifying the Desktop file as shown below (see 'Exec' value) seemed to solve this for most users here, but no luck. I am now using pkexec instead of lqxt-sudo, since this seems to be the recommended approach.
[Desktop Entry]

I've also tried building a policykit action as some posts suggested, but even when I give the program full access, there is still a delay on first launch:
<?xml version="1.0" encoding="UTF-8"?>
