I have installed Notion from Sphere on my MacBook (I have also installed Studio One 5, which appears to run perfectly) and I have an issue with very poor responsiveness.
The interface often doesn't seen to register trackpad clicks at all. Especially when I choose items from the Toolbar such as Show/Hide Piano, or Show/Hide Drum Library nothing happens until I scroll the screen slightly, whereupon, the tool appears immediately at the bottom of the screen. Without adding that additional touch of the scrollbar, nothing happens. I often have to click twice on all buttons to activate the feature. The Fretboard is particularly hopeless: some notes refuse to appear/sound then others will.
Basically, everything seems to work but with awful responsiveness. Reminds me of back in the day when I had 4MB of RAM in Windows 3.1.Unusable at the moment.
Other programs show no lag at all, even Studio 5. I have Notion on my iPad and iPhone: works fine on both.
Anyone had experience of this and hopefully a solution?
