This issue would only manifest when a custom task runner was being used with a custom compositor. Both were tested separately but not together. A new test has been added for this. We still create the GPU thread merger unnecessarily but I can patch that later. I also cleaned up the existing custom task runner test to not submit tasks on a dead engine as they just log errors unnecessarily. Filed new: https://github.com/flutter/flutter/issues/38844
