Moving the GX Corner to sidebar solved my problem.

@stoogiemeister said in Tab Dragging onto another Window:

The answer is to drag the tab from main window to your 2nd window on 2nd monitor, but the trick is to hold click and hover it above the + symbol on the other screen window for up to 2 seconds, you will then see the tab underneath move which means u can let go of left click now to drop it. Repeated test heaps of times, it works. nothing else works however

This is the right solution.
