Created attachment 32913 [details] 3d transformations failing to work I read the recent WebKit blog entry about 3d transformations http://webkit.org/blog/386/3d-transforms/ so I downloaded a nightly to try them out. When I try the examples linked, however, none of the 3d transformations seem to work. There seem to be 2d transformations applied, and animations are running, but everything appears flat. I've attached a screenshot showing what it looks like. I'm not sure what information will be helpful for debugging this; let me know and I can add more details.

Are you sure you're running the nightly build, and not the system Safari?
Yes, I checked several times that I was running the WebKit nightly download. It has the icon with the gold border and "Check for WebKit Updates..." is available in the "Safari" menu. I tried choosing that option, and it tells me that I'm on the latest version of the nightly. If there's any way for me to check that the the nightly rendering engine is actually being linked in properly, let me know; I don't know if there is a way to verify that. lsof shows that the process has "/Users/lambda/Desktop/WebKit.app/Contents/Resources/WebKitNightlyEnabler.dylib" open, so it appears that it should be linking in the nightly version of WebKit.
What does defaults read com.apple.Safari WebKitAcceleratedCompositingEnabled return when you run it in Terminal?
$ defaults read com.apple.Safari WebKitAcceleratedCompositingEnabled 2009-07-17 12:07:02.912 defaults[354:10b] The domain/default pair of (com.apple.Safari, WebKitAcceleratedCompositingEnabled) does not exist Setting this to either 1 or 0 does not affect the behavior. Following are all of the defaults for Safari which begin with WebKit: WebKitCacheModelPreferenceKey = 2; WebKitDefaultFixedFontSize = 9; WebKitDefaultFontSize = 14; WebKitDeveloperExtras = 1; WebKitDeveloperExtrasEnabledPreferenceKey = 1; WebKitDisplayImagesKey = 1; WebKitEditableLinkBehavior = 4; WebKitFixedFont = Monaco; WebKitInspectorAttached = 0; WebKitInspectorAttachedViewHeight = 379; WebKitJavaEnabled = 0; WebKitJavaScriptCanOpenWindowsAutomatically = 0; WebKitJavaScriptEnabled = 1; WebKitPDFDisplayMode = 1; WebKitPDFScaleFactor = 1.486642; WebKitPluginsEnabled = 0; WebKitPrivateBrowsingEnabled = 0; WebKitRespectStandardStyleKeyEquivalents = 1; WebKitShouldPrintBackgroundsPreferenceKey = 0; WebKitShrinksStandaloneImagesToFit = 1; WebKitShrinksStandaloneImagesToFitKey = 1; WebKitStandardFont = "Lucida Grande"; WebKitTextAreasAreResizable = 1; WebKitZoomsTextOnly = 0;
If you make a new user account on the machine, does it work there in the nightly? Do you have any other machines nearby that you can test on?
It does indeed work if I log in as a different user. It also works if I build WebKit from Subversion (r46036) and run it using WebKitTools/Scripts/run-safari in my normal account.
This has to be a configuration issue on your system then.
