Android Studio 3 - Constraint layout editor broken

Question

I\'m using Android Studio 3.0 (updated to canary 4 today) on macOS for a side project and recently (not sure really when) the constraint layout editor stopped working proper

Answer 1

Which gradle version are you using? Also, support lib 26.0.0-beta2 has an issue with studio, if you are using it you should downgrade to beta1 to use the editor.
