I have version 3.0.0.2041 of the SonarLint plugin with IntelliJ 2018.2, and when SonarLint has scanned a file, if I hover over one of the issues, it shows the same feedback three times. This triplicate continues if I click the “more…” link. I’ve attached an image showing the first pop-up. Is there something that I can change on my end to make it only show the info once?
Hello Ben, thank you for your feedback.
I have been able to reproduce this issue with SonarLint for IntelliJ 3.0.0.2041, and not with the current version (4.1.0.3312 as of writing, still compatible with IJ 2018.2). I suggest that you update to this latest version, we have worked on quite a few fixes and new features in 2 years 
Ok, good to know. I’ll try to get the plugin updated internally.
