891d1c8d9a920432b96bb52e1aafe554c408a120 [GTK][WPE] Fix SkiaCompositingLayer filter rendering under transforms
not a security fix
confidence 0.12
signal score 7.47
Source/WebCore/platform
Classified as not security-relevant.
Triage note: Reworks SkiaCompositingLayer filter/backdrop painting to render the subtree in the layer plane at a fixed scale (paintWithFilter/filterSurfaceScale/layerPlaneClipBounds), with surface-size caps at maxTextureSize/2. Rendering-correctness rework for perspective; size caps are feature-internal, no identified memory-safety bug.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
