First, I don't recommend changing the win10 theme. That suggestion was just to show that the 'gaps' you see are not really gaps. Just that the default Win10 theme makes the resizing borders invisible, but those borders still do exist even though you cannot see them.
Based on your first screenshot, it looks like .eu client is running in 100% scaling, and .es is running in 125%. How many monitors do you have? And what is your scaling in Windows?
I also am not sure about using Win7 compatibility mode. I would turn that off, and try #2 on this page instead:

And I'm glad moving to win10 has fixed iPoker. I am still working on trying to figure out a new scan mode that might work on win7, but there's no guarantees. And Microsoft is going to be ending support for Win7 next month anyway, so really most people should be upgrading asap
