There is huge memory leak in Metal.
It can be observed with a slightly heavy animating sample like ColorfulCircles sample in Ensemble.
The memory consumption increases constantly at a rate of 1 GB in 15 to 20 minutes.
The rate becomes 5 to 10 GBs in 1 minute if METAL_DEVICE_WRAPPER_TYPE is enabled.
