Clear filter or assign a new one does not work on Androíd

#1

I use a ColorMatrixFilter filters to highlight a bitmap of a button. This works, but when I try to clear the filter or apply a new one the new filters does not show on Android. It still keeps the ColorMatrixFilter.
But when I add an extra

Bitmap.cacheAsBitmap = false

before assigning the new filter it works. On Flash the Bitmap.cacheAsBitmap = false is not necessary and everything works as expected.
