I noticed the _timeline/TextInputTween sample was rendering in the upper right hand corner on Mojave and High Sierra (haven’t checked other recent versions). I tried setHighDensityDisplayEnabled() but that didn’t seem to work. Is there something I’m missing?
Did you try setHighDensityDisplayEnabled( false )?
Got it working: I needed setHighDensityDisplayEnabled() to be true but I also needed to pass prepareSettings to the CINDER_APP macro. Time for a pull request…
