Hi Lauren --

Nope. It just happened by chance. And only in a -f build. Hmm...

   DisplayScreen setNewScreenSize: (1024 at 768) * 1.´
   self currentWorld doOneCycle.
   DisplayScreen setNewScreenSize: (1024 at 768) * 2.
   self currentWorld doOneCycle.

] repeat.

Maybe it is a (Metal) texture allocating/freeing issue ...

Hi Lauren --

Thanks for reporting this. I was able to reproduce the issue. I am looking into it right now.

Hi List,

What the subject line says. I had just toggled the UI scale between
200% and 300% and back again and the window had shrunk, so I resized it
to maximize it again and the VM aborted.

The the last call from the VM was in
-[sqSqueakOSXMetalView loadTexturesSubRectangle:]
-[sqSqueakOSXMetalView drawRect:]
