Hello Salman,
I fact, I thought I can have two windows on my Rpi and for example, see Kstars in the first windows and Ekos in the second. I did that with my previous version (32b).
I can't retrieve this function now and I think it's not a problem of vnc.
It's not a problem of Stellarmatte so no problem.
Thank you,
Frank
You can check the settings whether Ekos have an independent window on not.
Also you may need to resize the windows and keep them splitted to two Views. If that helps.
