If you set wrap_windows ("With a dragged window") from FALSE to TRUE, tiling stops working until after you restart xfwm4. It's not really a critical issue, but I thought that both options could be used in combination now? http://git.xfce.org/xfce/xfwm4/commit/?id=5cb4d8032bb32a3d64ac9b6a84427203f058473f
Sorry I cannot reproduce this. Looking at the code, both options are totally independent, so I don't see how this could happen...
Very strange, but with a clean install from git master I can't reproduce the bug either – everything works as expected now. Sorry for the noise, marking as invalid.
