All tools can use it but are not part of the official Pharo6 release. This does not mean that Bloc doesn't work.

On top of Bloc is Brick, with the widgets.
This project is meant to have Pharo support whatever surface and resolution one is throwing at it. There are commercial projects underway using it for tabletop style UIs.

To try this out: https://github.com/pharo-graphics/Tutorials
So, all of Moz2D style stuff is working in Bloc

The upshot seems to be that they're working on it, slowly.
If you don't mean actually unusable (e.g. artifacts, too tiny, etc) then it sounds like a really superficial issue...
It's a volunteer non profit project. If people haven't done, clearly the don't have the time to do it over other things.
Tsk, tsk-ing them for not having fixed everybodys and anybodys pet peeves is beyond meaningless.
It's not like random non-Pharo using programmers are entitled to anything. Or like anybody forces them to use the platform.
If they don't like it, it's rather "don't let the door hit you on your way out".
If, otoh, they want to use Pharo they can. If they find that future important, they can help build it.
But I don't think entitled criticism helps or is welcome in any community project.
It's easy to point at anything and ask them why they haven't done it yet, and that it's this "mindset" that keeps them small.
As if if they had a different mindset they'd also have magical resources.
I'm just restating the obvious.
I should do that for my Surface Pro 4. But that would be a specific build.
It's a bit of a common point of frustration for me, because I've had the same problem with Squeak, Dolphin, and several other flavors of Smalltalk that I've tried. Because of this, the only version of Smalltalk that I've actually been able to work on has been GNU Smalltalk in a terminal.
This is disappointing, because I really want to play with it more. Can anyone recommend a modern version of Smalltalk with a GUI that has HiDPI support?
