The earlier reduction was not sufficient for all cases.
If the min width is totally removed, it makes the buttons too
small in portrait, causing wrapping. Forcing to 0.5 weight will
make it too wide in landscape.

Also reduce the min width of the buttons because the horizontal space
available has reduced.
