Drag a window to the edge to tile it. Release the mouse button. Drag it back to the screen to untile it. One of the window sizes is restored but the other is not. E.g. after tiling a window at the size of the screen, untiling it restores the window height but not the width. After tiling it to the top of the screen, only width of the window is preserved.
I have the same problem. For example, when I tile thunar, and then move it back again, it changes it's previous windows size. It doesn't has the size I like it anymore, so I have to change it everytime, and it's quite annoying. And it doesn't happens only with thunar. The best would be to restore the previous size of the window, that had before to do the tiling, like in other DE.
