In my test Xclic works in few cases, when there is a black background seems to not working.
I often notice that clicking near the item to click in my opinion Xclic is not a good command to use because it often does not work properly.
It would be useful to create an alternative command that can execute commands precisely such as sendkeys that in ui vision works very little, but sendkey on Katalon Recorder works a little better and allows you to emulate the keyboard more precisely.
Currently I am no longer using Xclic because it is more errors and problems than gives benefits, if you look in the forum there are so many reports of errors of the Xclic command.
Here a case but in the forum there are more report of this problem
