And after all these years, still no fixes for high-DPI displays. The UI is still pixely and slow. Perhaps I should take Fable and try myself, this was the only bug I cared about and it is not solved after 10 years at least.
Cuis Smalltalk has full high-DPI support as its GUI is based on vector graphics: https://cuis.st/
The UI has been a huge impediment in my getting into Squeak development. Every couple years I decide I will try it again, and then see that very little has changed.
It's a shame. Smalltalk/Squeak/Pharo was supposed to be the future, but it feels like an IDE stuck in the 90's.
yeah, after all these years, they are waiting for your contribution. you really should go at it with Fable.
Use the Glamorous Toolkit.
Same, I've been tracking this and Pharo for high-DPI fixes. Pharo is working on a new graphics stack that is intended to address this as well, but until then no high-DPI support.
