Hi I experience a critical?? bug… Test Environment - OSX 10.11.6 - Xcode 8 - iphone 5s 9.3.5 - UE 4.14.0 (PV3 install from launcher) - bSupportsMetal=True in DefaultEngine.ini ( Support Forward Rendering with Metal (A7 and up devices) ) * * * How to reproduce bug 1. Make TestApp ( I make cpp project, just 2 text box, and 1 Button(click event with launch URL [https://www.google.com](https://www.google.com)) ) ![114770-btn0.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/9/c/d9c04f4c7efad006007619648a28c79c696ce9ed.png) 1. Launch this app With iOS Device. 2. ![114769-b000000.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/a/2/3a254c758fbeb5740a4373633db3fbcef640dda3.png) typing any character with text box simply. 5. execute button and open browser app. 6. return to TestApp. 7. repeat 3~6 until crash. crash is randomly occur when doing [3.] with virtual keyboard. (Not 100%) I expereince this bug UE 4.11~4.14. And there is no problem when bSupportsMetal=False. * * * Xcode Crash Log ``` Version: 0.6 (1.0) Code Type: ARM (Native) Parent Process: launchd [1] Date/Time: 2016-11-14 17:16:34.34 +0900 Launch Time: 2016-11-14 17:13:47.47 +0900 OS Version: iOS 9.3.5 (13G36) Report Version: 105 Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Triggered by Thread: 20 Thread 20 name: Dispatch queue: com.apple.IOAccelerator.CommandQueueCompletion Thread 20 Crashed: 0 libsystem_kernel.dylib 0x236ffc5c __pthread_kill + 8 1 libsystem_pthread.dylib 0x237a5b47 pthread_kill + 63 2 libsystem_c.dylib 0x236940c5 abort + 109 3 test414 0x0049f7d3 0x8000 + 4814803 4 test414 0x00622941 0x8000 + 6400321 5 test414 0x005c95f9 0x8000 + 6034937 6 test414 0x0398d8ab 0x8000 + 60315819 7 test414 0x039cc297 0x8000 + 60572311 8 Metal 0x2580e1d1 -[_MTLCommandBuffer didComplete:error:] + 213 9 Metal 0x257e8893 -[MTLIOAccelCommandBuffer didComplete:error:] + 239 10 Metal 0x258117cb -[_MTLCommandQueue commandBufferDidComplete:timestamp:error:] + 255 11 Metal 0x257f772b __53-[MTLIOAccelCommandQueue submitCommandBuffers:count:]_block_invoke21 + 43 12 IOAccelerator 0x2578eb91 ioAccelCommandQueueBlockFenceCallback + 37 13 IOKit 0x23cc35e5 IODispatchCalloutFromCFMessage + 257 14 IOKit 0x23cc3659 _IODispatchCalloutWithDispatch + 25 15 libdispatch.dylib 0x23609287 dispatch_mig_server + 363 16 libdispatch.dylib 0x236165bb _dispatch_source_latch_and_call + 2043 17 libdispatch.dylib 0x23605bff _dispatch_source_invoke + 739 18 libdispatch.dylib 0x2360d9ed _dispatch_queue_drain + 593 19 libdispatch.dylib 0x23606e17 _dispatch_queue_invoke + 283 20 libdispatch.dylib 0x2360f20d _dispatch_root_queue_drain + 401 21 libdispatch.dylib 0x2360f07b _dispatch_worker_thread3 + 95 22 libsystem_pthread.dylib 0x237a2e0d _pthread_wqthread + 1025 23 libsystem_pthread.dylib 0x237a29fc start_wqthread + 8 Nov 14 17:16:24-93 test414[740] : Fatal error: [File:/Users/build/Build/++UE4+Release-4.14+Compile/Sync/Engine/Source/Runtime/Apple/MetalRHI/Private/MetalCommandList.cpp] [Line: 47] Command Buffer Frame3540 Failed with Timeout Error!

if you couldn’t open project, make new project(4.14, test Cpp project) and copy from only content folder from that. There is Map file, UMG widget blueprint file. Honestly, I can not understand how impossible it is. because, it was almost clean project. it was just added blueprint, map. ---
