This is required by tests like svg/filters/filter-empty-g.svg Unfortunately, this is supported inconsistently, or not at all, across the various underlying graphics engines (CG, Skia, Windows GDI, etc.) Various workarounds currently exist. For example, on Windows, an underlying 1x1 image is created; see BitmapPlatformDevice::create inside skia/ext/bitmap_platform_device_win.cc However, a more uniform, higher-level solution is necessary. 256948 1 ctruta 2010-07-27 17:15:50 -0700 Let us not forget to remove the following exclusions upon submitting the fix for this bug: LayoutTests/platform/chromium/test_expectations.txt LayoutTests/platform/mac-leopard/Skipped: (svg/filters/filter-empty-g.svg) See bug 41808 and bug 42802. 2196133 2 karlcow 2026-04-01 20:58:30 -0700 This would need to be more specific. Basically since 2010 a lot of things have been rewritten and some of the things mentioned above do not exist anymore in WebKit. Probably this would deserve a more specific fresh bug.
