I guess what you're seeing is a side effect of xtext's expose event
buffering. The problem is, everytime you switch a tab, xtext gets a draw
and expose event, so it ends up drawing itself twice. To get around it,
there's some very simple buffering of the events, try this patch which
disable that. Of course, with this patch applied, it'll draw itself twice
when switch tabs again :(
