Looks to me as if the window is moved offscreen and then quickly again
moved to its "proper position". I'd look at some tracing output to
figure this out, e.g. via xtrace (also known as x11trace) on your WM. Or
on an app in question to see where it is moved to.

Alternatively, you could do some printf-debugging and print the window
position before every xcb_configure_window() call to see where it is
being moved to.

I can't really read objc, but... where is this moving of windows
implemented? I tried searching for xcb_configure_window(), but all the
hits don't seem relevant to "move by mouse".
