(Some floating windows have their last position remembered and, the next time they are drawn in floating mode, are positioned where their last floating position was.

However, when these floating windows are positioned for the first time after being killed, the X-axis (horizontal) is correctly aligned but the Y-axis (vertical) is not. The floating windows are consistently drawn such that the top of the window's title bar is at the bottom of where it's title bar was last time. For me, that's a total of about about 20px.

Example 1:

1. Open Geany.
2. Switch to floating mode.
3. Move it to a desired position.
4. Quit Geany.
5. Open Geany.
6. Switch to floating mode.
7. Note that Geany is now positioned lower than it was when it was exited in step (4).

Example 2:

1. Open the connection settings window in Firefox (Preferences > Advanced > Network > Settings). It's window type is floating by default.
2. Exit the window 9 ("cancel" is fine).
3. Re-open the window, note that it's positioned lower than last time.

This isn't a big deal, but it gets annoying for windows that are frequently killed and then brought back into floating mode. For example, on Firefox I bring the "Connection Settings" window up often and every 10 or so times (about every week) the window migrates low enough that it's off the bottom of the screen back up to the top. I think this also applies to certain JavaScript dialog boxes.
