The issue, judging soley by the video is being caused by the browser window being at a small size with the page being scaled up. Gridder, does move so the image clicked with within the browser viewport but because of the reason cited (best guess) the browser viewport is too small to fit the info panel of the entry clicked.
There is no setting to remove this, however, removing a single line in Gridder’s JavaScript file will stop it from trying to moving the entry to be within the browser viewport. here’s how:
Open the delete the gridder.min.js
file found here:
../wp-content/plugins/connections-gridder/
Now, open the gridder.js
file found in the same folder and remove the following line:
$( _self._scrollTo() ).animate( { scrollTop: _me.position().top }, 0 );
Save the file and upload it overwriting the original.
You will very likely have to force refresh your browser so the new version will be used instead of the local copy the browser has it its cache.
Hope that helps!
