Ok, I managed to somehow make 8.2.0 work.
This is a corner case, this time it is broken when the DE it is set to a dark theme (Breeze dark in my case).
Affected versions 7.9.0 up to 8.2.0.
Having the system set with a general dark theme, Katalon is stuck, apparently when trying to open the popup expecting user confirmation for something like ‘are you new user’ (immediately after the activation step)
I set my global theme to a light one, launched katalon, selected one option and closed that window.
Now that popup won’t appear anymore, so I switched back to the dark theme and is working fine.
Could be related to this bug which I saw it mentioned in certain css file:
[ibus@localhost Katalon_Studio_Linux_64-8.2.0]$ grep -R splash .

@duyluong @ThanhTo kindly pass this info to the dev team.
Until you figure out how to properly fix it, please disable this annoying ‘feature’ .
@kazurayam @Russ_Thomas please one of you with powers, re-open:
and move this post there since it seems like it is somehow related (it is caused by the eclipse engine upgrade)
