When the client window is positioned in some specific coordinates (like x 14 y 49), the window content can be translated to the top-left direction on top of the window frame. This problem has been reproduced only on GNOME Ubuntu 24 starting from shell version 46.0 and it's reproducible with any application, for example `xev -geometry 200x200+14+49`. Version of NoMachine client is not relevant.

Every NoMachine window stores the current position and geometry in order to restore it when starting, so once the bad position is saved, the issue will consistently occur when the same window is opened.

As a workaround, move the window by dragging the small section of visible title bar, or press Alt+F7 to trigger the window move action.
