After 284617@main, GraphicsContextCG::drawNativeImageInternal() has two calls to CGContextStateSaver::save(). The first one is called before clipping the context to partially display the image. The second one is called before setting the headroom of an HDR image. If these two calls happen in the same session, the second call will fire the assertion `ASSERT(!m_saveAndRestore);` in CGContextStateSaver::save(). 2065971 1 sabouhallawa 2024-10-07 15:09:25 -0700 rdar://137402152 2065985 2 sabouhallawa 2024-10-07 15:31:50 -0700 Pull request: https://github.com/WebKit/WebKit/pull/34798 2066063 3 ews-feeder 2024-10-07 18:25:54 -0700 Committed 284798@main (58072722f0cc): <https://commits.webkit.org/284798@main> Reviewed commits have been landed.
