Comment 9 for bug 1849135

I experience this bug, too. What is interesting is that even if:

1. I hide the top bar of gnome shell with extension,
2. Disable dash-to-dock and
3. Bring a window so it occupies the most top-left corner (or maximize it),

the windows does not react if I click the corner. In this case the expected behavior is to grab and drag the window.
