Cool. Nice to know.

Yes. That is an issue of the OpenSmalltalk VM, and any application that 
does not declare to be "Retina Aware". For these, MacOS uses a lower 
resolution framebuffer that is scaled up by the operating system. This 
affects (at the very least) all systems that run on the OpenSmalltalk 
VM, i.e. Squeak and Pharo will also answer that extent. There is some 
limited possibility of modifying this "emulated display" size in System 
Preferences / Displays / Resolution, although none of them gives true 
native resolution.

I use the EasyRes application, to set the mac display to true native 
resolution. But I only use it this way while using Cuis, because 
everything else looks terribly small. Amazingly this is not needed when 
running Cuis in a Windows or Linux VMWare VM in the Mac, so this is also 
a possible alternative.

The real fix would entail fixing the VM. I think it shouldn't be too 
hard to add a command line option or a VM setting of some kind to tell 
MacOS we really know what to do with the pixels we are given!

Thanks for reporting. I'll look into this. But this is new and still 
experimental. It might take a little time until everything works as 
smoothly as in the BitBlt based world.

My pleasure!
