When I use pencil or highlighter of PencilKit on debug, and write it quickly, it'll crash. But it's fine on release
the error message:
-[MTLDebugCommandBuffer lockPurgeableObjects]:2103: failed assertion `MTLResource 0x2816cd0a0 (label: (null)), referenced in cmd buffer 0x11a041400 (label: Live rendering command buffer) is in volatile or empty purgeable state at commit'
is it a bug, or am I making something wrong?
