"border none" breaks window resizing

[resloved]

Forgot about this bug that was posted in the Airblader/i3 pull request so hopefully an issue is a little easier to remember.

when removing window borders with something like
bindsym $mod+Shift+space floating enable, border none
it breaks window resizing with mouse or resize mode. This is not just floating windows, but tiled ones too

My response at the time:

After some quick testing its pretty easy to reproduce. The floating is unrelated, you can just bind border none and the same problem comes up. This doesn't seem to occur when you just set border none using for_window so actually changing the border styling is important. I imagine it has to do with the pixmap being updated when the borders are normal, but after the change the window still uses the rounded/masked pixmap and it doesn't get updated. I'll try to take a look at this sometime this week.

Past me was very confident about "sometime this week"
