(From bug 20865)

Moving any Steam window by its own decorations (never the window manager's)
often results in the window moving twice as far as it should.

Dragging windows to a new position works fine, but on release of the left mouse
button, the window jumps the same distance you moved it beyond where you moved
it to.

This effect occurs most often with short, jerky moves. Waiting before releasing
the LMB may result in proper behavior.

This bug occurs with or without a virtual desktop. However, WITH a virtual
desktop, it DOES occur when resizing. (Without a virtual desktop, resizing
works properly.)
