1227236

Regression

Yes

Crash on MTLReportFailure.cold.2 + 43 when running Build with Graphics Jobs enabled

Metal

-

Reproduction steps:
1. Download the Build "Case_1227236.zip" from the attached link
2. Run the script "rustcrashtest.sh" located in the build
3. Wait for the Build to load and let it run for a while

Reproducible with: 2019.3.3f1, 2019.3.5f1, 2019.4.7f1
Not reproducible with: 2019.2.21f1

First lines of the stack trace:
Thread 26 Crashed:: Metal Submission Thread
0 libsystem_kernel.dylib 0x00007fff6ddfe33a __pthread_kill + 10
1 libsystem_pthread.dylib 0x00007fff6debae60 pthread_kill + 430
2 libsystem_c.dylib 0x00007fff6dd85808 abort + 120
3 libsystem_c.dylib 0x00007fff6dd84ac6 __assert_rtn + 314
4 com.apple.Metal 0x00007fff3917f729 MTLReportFailure.cold.2 + 43

Notes:
1. As only a Build was provided, we are unable to test the other streams if they are affected
2. Takes around 4-5min to crash after the game has fully loaded
3. The user mentioned themselves that the issue reproduces with Graphics Jobs enabled
4 The Unity log file does not contain a stack trace, only this error:
"-[MTLIOAccelCommandBuffer validate]:208: failed assertion `commit command buffer with uncommitted encoder'
-[_MTLCommandEncoder dealloc]:70"
5. In order to run the script, on macOS, open a Terminal window at the Build's folder, and run "sh rustcrashtest.sh"
6. After the crash, the log file will be located in the Build folder "output_log.txt"
