compositing/debug-borders-dynamic.html [ ImageOnlyFailure ] The image diffs are here: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r237249%20(8526)/compositing/debug-borders-dynamic-diffs.html This seems to have been caused by r236401 (blame me!!). Weirdly enough, the indicators weren't working at all before my patch and the test wasn't failing then... anyway, the problem is that the indicators are drawn in yellow instead of green. Not sure if they should be green and there's something wrong in the code, or they should be yellow and we need to rebaseline the test.
