I add this issue here so I won't lose track of it.
When resizing windows in floating mode, sometimes adwm loses the state of the window geometry. For example, the effect can be seen by following these steps:
Place a workspace in floating mode (Alt F).
Open a roxterm window.
Increase the font size using (Shift Ctrl +): the window increases in size properly.
Vertically maximize the window (Shift Ctrl Up): the window maximizes vertically, but the width of the window goes back to its original width, which is incorrect.
