Annoying unclear "Close all" in recent apps.

[MoRadwan]

The "Close all" button is not clear at all and has no solid frame, for example same as in landscape mode, and sometimes it's confusing. 

Please modify it!

Portrait vs landscape

Agreed, almost looks greyed back

It wouldn't be there at all if there was only one app, I think there's a point where people just get picky

Not an essential change, albeit possible a simple change.
