I use Barts and HotNiPis excellent multstte switch a lot - but i nearly always end up with Dashboard alignment issues - in particular once this is introduced onto a dashboard page i seem to end up with various blocks of text/groups being hidden behind others.
I can usually solve this by dragging things around until i find a comfortable layout - but not this time
As far I know, it can happen if you make many many groups having different sizes. And the actual content of the group doesn't matter at all. The underlying grid system just fails to calculate positions for things at some point.
You may test it by temporarily replace the multistate switch with something else but keep the sizes.
