It's a bug in JMeter use one of the following workarounds:

  1. Change "Look and Feel" to something which doesn't contain Darklaf

    enter image description here

  2. Add the next line to user.properties file (lives in "bin" folder of your JMeter installation)

    jmeter.laf=CrossPlatform

  3. Downgrade to Java 8

  4. Try Nightly Build of JMeter

  5. Add --add-opens=java.desktop/sun.awt.shell=ALL-UNNAMED to this line of jmeter.bat startup script
