Summary [chromium] Linux: compositing test failures due to differently sized layers

Reported 2010-10-20 15:44:23 PDT
There are a few failures of compositing/ layout tests when run on Linux in DRT / NRWT due to differently sized layers than on Windows. Since the layout code should be platform independent, it is unclear why these differences are present, and they need to be investigated. compositing/geometry/limit-layer-bounds-positioned-transition.html compositing/geometry/limit-layer-bounds-transformed.html compositing/geometry/vertical-scroll-composited.html

How different are the values? I don't think scrollbars are exactly the same size on windows vs linux.

The values are very different, and indicate something like failure to clip the layer to the visible window or similar. It's possible there were code changes between the times these two baselines were generated that would affect the results. --- /usr/local/google/home/kbr/src/chrome6/src/webkit/Debug/layout-test-results/compositing/geometry/limit-layer-bounds-positioned-transition-expected.txt +++ /usr/local/google/home/kbr/src/chrome6/src/webkit/Debug/layout-test-results/compositing/geometry/limit-layer-bounds-positioned-transition-actual.txt @@ -1,9 +1,9 @@ Text here (GraphicsLayer - (bounds 800.00 600.00) + (bounds 1429.00 585.00) (children 1 (GraphicsLayer - (bounds 800.00 600.00) + (bounds 1429.00 585.00) (children 3 (GraphicsLayer (position 29.00 29.00) --- /usr/local/google/home/kbr/src/chrome6/src/webkit/Debug/layout-test-results/compositing/geometry/limit-layer-bounds-transformed-expected.txt +++ /usr/local/google/home/kbr/src/chrome6/src/webkit/Debug/layout-test-results/compositing/geometry/limit-layer-bounds-transformed-actual.txt @@ -1,9 +1,9 @@ Text here (GraphicsLayer - (bounds 800.00 600.00) + (bounds 1329.00 585.00) (children 1 (GraphicsLayer - (bounds 800.00 600.00) + (bounds 1329.00 585.00) (children 3 (GraphicsLayer (position 129.00 29.00) --- /usr/local/google/home/kbr/src/chrome6/src/webkit/Debug/layout-test-results/compositing/geometry/vertical-scroll-composited-expected.txt +++ /usr/local/google/home/kbr/src/chrome6/src/webkit/Debug/layout-test-results/compositing/geometry/vertical-scroll-composited-actual.txt @@ -1,4 +1,4 @@ -layer at (0,0) size 814x1014 +layer at (0,0) size 962x1122 RenderView at (0,0) size 785x585 layer at (0,0) size 785x616 RenderBlock {HTML} at (0,0) size 785x616
