Even though the theme variable for locked grid separator is set to 0, when resizing the locked column, a new border appears randomly. It seems more like an empty space between the grids.
$grid-lockable-separator-border-width: dynamic(0);
Any suggestions?
First of all you do not have to use dynamic, which only tells Senchas SCSS that it could be overridden in deeper spheres.
