metal new render pipelinestate with pipelinestate cache have memory leak at first time

it's my ue4 game project . The first time the pso is created, the process of moving the link, the second time the result is directly read from the PSO cache File. The first time to create a PSO and go through the linking process will generate a lot of memory that cannot be released. I would like to ask if there is a release plan for this piece?

This is memory allocated by the MTLLibrary for a MTLFunction object. The engine/app should not need those objects once a PSO has been created. When those objects get freed, that 75MB will be freed.

    -- did you mean the MTLFunction object?
