Starting Leadwerks with e.g. awesomewm or dwm (even in floating mode) makes the splash screen flicker and move to the top left of the screen until you try to resize it, at which point it changes to a maybe 3x20 pixel window. Then you'll be left with a big window with something looking like an empty toolbar titled "Leadwerks Editor - <untitled>", the tiny window that's now titled "<untitled>", and two about 1 by 1 px windows for the Project Manager and New Project window.
The awesomewm config is the default, so this should be easily reproducable, but if not I'll gladly help debugging this.
