I'm using the Windows 2018.3 build of the Snapdragon profiler with a Google Pixel phone running Android 9. I have a small tool which loads a serialized frame from a larger application and plays it on a loop so I can use profiling tools on a shorter development cycle.
However, I've discovered that when I use the KHR_debug extension functionality, attempting to take a snapshot causes a crash. glPushDebugGroup and glPopDebugGroup are available in OpenGL ES 3.2, and glPushDebugGroupKHR and glPopDebugGroupKHR are available in any device with the KHR_debug extension.
My Pixel supports both, but no matter which I use, attempting to take a snapshot when these functions are in use crashes Snapdragon Profiler with no error message.
