FirstMeaningfulPaint event not getting triggered on first navigation

[NivedhaSenthil]

The lifecycle event FirstMeaningfulPaint is not getting triggered always for the first navigation done immediately after opening browser. But gets triggered instantaneously when trying to navigate for the second time. Happens only in particular environment.
Browser is opened with following args in clean state.

        '--remote-debugging-port=port',
        '--disable-features=site-per-process,TranslateUI', 
        '--enable-features=NetworkService,NetworkServiceInProcess',
        '--disable-renderer-backgrounding',
        '--disable-backgrounding-occluded-windows',
        '--disable-background-timer-throttling',
        '--disable-background-networking',
        '--disable-breakpad',
        '--disable-default-apps',
        '--disable-hang-monitor',
        '--disable-prompt-on-repost',
        '--disable-sync',
        '--force-color-profile=srgb',
        '--safebrowsing-disable-auto-update',
        '--password-store=basic',
        '--use-mock-keychain',
        '--user-data-dir=user-profile',

Setting proxy server args did not help for this case.
