Hi Christian,
I think it might be because the map isn't aware that its container is being resized.
You may have to write a custom event listener using the splitter.
When the splitter is moved, your event listener would resize the map div (and the map).
If you didn't want to use a jQuery module, I know DOJO has splitter functionality built in using ContentPanes and BorderContainers. The map would automatically resize when its ContentPane is resized.
var resizeTimer;
            $('#mainSplitter').resize(function () {
                clearTimeout(resizeTimer);
                resizeTimer = setTimeout(function () {
                    map.resize();
                    map.reposition();
                });
            });
