What happened to scrcpy.... or samsung
Did not work Properly on Arch linux with samsung dex alternative like above image
When i Open `scrcpy` commend it work proper as mirror ,
But When i am using `scrcpy --new-display` it does not work normally,
In my device everything has enabled like USB Debugging , multi window mode for all apps, desktop experience.
is these issue happened by Scrcpy or Samsung Device?
I did know.....!

Start by reproducing the reported behavior on Arch Linux with the Samsung device, comparing `scrcpy` with `scrcpy --new-display` and checking window mode and recent-apps behavior. Confirm whether the problem is reproducible in scrcpy or specific to the Samsung device; done means the cause and expected behavior are clearly established.
