Client 1.9.1 - increasing the size of the window

I found an error in the client - after increasing the size of the window, 2 of 4 cameras disappear from the screen

I’m Using:
NetCamStudio 1.9.1
Windows 10 pro - version 1909

Oh, yes. Here too.
I have to switch view, forth and back, to get back all cameras.

Yes that´s correct. Just click on 2x2 matrix again or click on a video and click again and correct view is back. I forward this.
