qt: prevent window jumps on resize (X11) On X11 with Qt < 5.10, a resize request invoked XMoveResizeWindow() (see 0285ba4eeaa55608573a48e50a036ee2b437ae8b), which both moves and resizes. To avoid moving, it was called with the current geometry() coordinates as position arguments. However, the calculated position may be wrong when several displays have a different devicePixelRatio(). As a consequence, on a secondary display, every (automatic) resize of the window made it jump to unexpected locations. To avoid the problem, just call XResizeWindow(), so that the window is not moved at all.
