Comment 3 2020-07-27 23:41:19 PDT

TextureMapperLayer::computeOverlapRegions has the following code: > boundingRect = m_layerTransforms.combined.mapRect(boundingRect); This code calculates a tranformed bounding rect. The original bounding rect was the the img size of thumbnail. It was 187x132. Then, it was transformed into 650749x156033. Why does it apply 3d transform to calculate a overlap region?

Thank you for the review, KaL. Addressed the point. This patch makes compositing/clipping/border-radius-stacking-context-clip.html pass unexpectedly. This seems regression, not progression. I will check it.
