Caused by: com.kms.katalon.core.webui.exception.WebElementNotFoundException:
Web element with id: ‘Object Repository/xSale/DodajKontrahentaPage/DodajKontakt_btn’

I think I see why Ibus jumped at “headless” - I didn’t expect that error from this.
I’m now very interested in the CSS associated with the service-bar-fixed-wrapper:
Using DevTools, highlight that div-element and take another capture - make sure you capture the panels to the right which should show the CSS.
