Sorry it took me a few days to look at the dumps. Thanks for providing them! They all show the CPU waiting in the same place, waiting for the next frame to be rendered. This is place I would expect it to be waiting if the app is running correctly. It very much seems like literally everything is working correctly
the app is completely initialized, file watching is happening, rendering is happening
except the window never appears for you. I wish there were more symptoms to the problem, there really isn't much to go on. Are your video drivers up to date?
