This should essentially be thought of as your machine running out of resources after 16 contexts are active. 1008702 1 webkit-bug-importer 2014-05-12 13:23:14 -0700 <rdar://problem/16888465> 1008704 2 roger_fong 2014-05-12 13:26:51 -0700 Actually this: <rdar://problem/16888459> 1008750 3 231330 roger_fong 2014-05-12 15:12:43 -0700 Created attachment 231330 patch 1008813 4 231349 roger_fong 2014-05-12 17:15:36 -0700 Created attachment 231349 better patch 1008816 5 231349 dino 2014-05-12 17:25:01 -0700 Comment on attachment 231349 better patch View in context: https://bugs.webkit.org/attachment.cgi?id=231349&action=review > Source/WebCore/platform/graphics/mac/GraphicsContext3DMac.mm:118 > + return 0; return nullptr; > Source/WebCore/platform/graphics/mac/GraphicsContext3DMac.mm:123 > + return 0; return nullptr; > LayoutTests/webgl/many-contexts.html:13 > + for (var i = 0; i < size; i++) { > + canvii[i] = document.createElement("canvas"); > + canvii[i].width = 1; > + canvii[i].height = 1; > + var context = canvii[i].getContext("webgl", null); > + } Weird indentation. Also, I wonder if we should check that context == null at 1000 (assuming that we might raise the number above 16, but never to 1000). 1008826 6 roger_fong 2014-05-12 18:11:55 -0700 Committed
