Code completion is broken in IntelliJ after updating the IDE to v2019.2.1 (using the Linux version), and the Kotlin plugin to v1.3.50 with a new Kotlin Native project. No code completion dialog appears when editing a kts file, and attempting code completion in a kt file will cause the keyboard input to become garbled (eg some keys like A are not recognised in the code editor, and some are outputted as a completely different character) ☹️ 😡.
