@Sergey I have tested and the problem is the function DRW_gpencil_freecache(ob); is not called in this situation from BKE_object_free_derived_caches function. I don't know why and no idea where add this call to be sure the instances memory cache is cleared. Could you take a look?

Not sure if this bug exists in the refactored engine. I will test it.

So is this actually solved in the refactor? This was a big issue for some artists here, so better to double check it doesn't get lost.

I have tested the test file above in the refactored version and I'm unable to detect any memory leak. Also now, the engine does not need to call to BKE_object_free_derived_caches()function as before, so I think we can consider it as solved in refactored code.
