CrashLog_0134_2019-03-25_10-42-43-882.txt
This assertion assumes two scenes are identical in the composting thread in CoordinatedGraphicsScene::purgeGLResources. However, state.id is incremented in the main thread in CompositingCoordinator::flushPendingLayerChanges. https://trac.webkit.org/browser/webkit/trunk/Source/WebKit/WebProcess/WebPage/CoordinatedGraphics/CompositingCoordinator.cpp?rev=243163#L157 The reason why GTK port doesn't have this issue is RunLoop::TimerBase::stop in GTK port stop the RunLoop timer synchronously. If the RunLoop timer is firing, RunLoop::TimerBase::stop blocks until it finishes. This is the same reason why GTK port doesn't occur Bug 195550. This assertion has been introduced in Bug 188693.
