Problem scaling Nik Collection 3 in 4k display windows

Hi, i installed Nik Collection 3 and have a problem with the scaling and cant solve it, the window in photoshop wont let me move it or close it, i would like to close it because i cant edit/see anything behind it. Also the text is too small to read, how can i solve this? thankyou. Im using windows 10 and photoshop cc 2018, and a Dell XPS 15 4k display laptop.

There are known problems such as those you’ve pointed out. For more information, look at this thread.

I remember the scaling of the selection tool being reported by someone before, but don’t know the solution - nor do I know why DxO hasn’t been answering these questions here. Best to open a support ticket at
