      My current working version of makepad thats been running for days is using 90mb ram. And i find myself thinking, 90mb!? for what? I know its mostly metal buffers but still. I should profile this just for the fun of it. Maybe something leaks.

      When i resize makepad apparently my metal framebuffers don't 'free' immediately but with lag, spiking memuseage to 2gb temporarily. Its slicksmooth in resizing though, and after a second or two its back to its old memusage. Ill put it on the list to investigate.

      Its possible also its not 'real' memory its just the taskmanager being wrong about the video memory. Still its odd.

      Yeah, I ran into this too in piet-metal (I think it's in the piet-metal notes doc). My solution, not yet coded, is to round up the size so that the pace of allocations goes down when smooth resizing.

          Yea also, metal is the only API that you see in memory usage. Chrome with openGL doesn't get counted.

          Means my base visible memory usage is in the order of 100+ megs more than chrome just in visible video memory.
