I have a similar issue with wmctrl in 15.04. Trying to place a window in the top-left corner, right next to the launcher, doesn't work.
"wmctrl -r :ACTIVE: -e 1,0,0,1240,1034" will place the window about 5 pixels to the right no matter what. If I try to place a window on the top right corner "wmctrl -r :ACTIVE: -e 1,1280,0,640,360" it's 5 pixels below where it should be. I can't find any explanation and I can confirm it works in other desktops. Other operations like "wmctrl -r :ACTIVE: -e 1,1280,720,640,335" work as expected, though, it just seems to have something against the left edge and top edge.
I am not sure if this is the right bug to post into, but they are pretty similar so they might be related.
