| This tests verifies that filters work even on composited layers that fallback to rendering in software. |
| NOTE: It is using the fact that Safari can draw drop-shadows in GPU only if the filter is the last one in the filter chain. |
| First we apply the shaders using a composited layer, but compute the filters in CPU. Then we switch to compute them in GPU. |
| You should see three green rectangles slightly rotated and blurred. There should be no red and it should not crash. |
