>  found an easy solution for the bug where a ShowcaseView title which is longer than one line overlaps the detailText:
replace line 440 of the ShowcaseView.class, in the dispatchDraw(Canvas canvas) method with this:
Code:
canvas.translate(mBestTextPosition[0] , mBestTextPosition[1] + 12 * metricScale + (mDynamicTitleLayout.getLineBottom(mDynamicTitleLayout.getLineCount()-1)-mDynamicTitleLayout.getLineBottom(0)));
