As ICCCM 4.1.5 suggests, the WM may not send a synthetic configure notify event if the window is resized for real. In that case, the client needs to use the TranslateCoordinates() request in order to determine the position of its window in the global coordinate space.

I don't know exactly why the new code path had been enabled only with handful of WMs, perhaps it was done to play safe or as an optimization. But, in general, as the TODO comment and the ICCCM spec say, this code needs to be enabled regardless of the WM.

Can u assign the JBS to your name, its still unassigned.
