SPV2 raster invalidation rects (repaint rects) are wrong |
|||
Issue descriptionWith https://codereview.chromium.org/2770963002/ we can now render raster invalidation rects (repaint rects) using: --enable-slimming-paint-v2 --show-paint-rects This exposed a bug where we issue full-page infinite repaint rects every frame due to https://cs.chromium.org/chromium/src/third_party/WebKit/Source/platform/graphics/paint/PaintController.cpp?q=paintcontroller+package:%5Echromium$&l=669.

Update: this affects all pages. For example, about:blank has large repaint rects. https://crbug.com/698066 has been fixed so these are now visible with devtools.
