Clear this checkbox if you don't want to see these icons. Here's a list of the problems I myself encountered when using WebStorm with WSL2 (the problems are the same in any of their tools - WebStorm, P圜harm and IntelliJ): Example problemsWhenever WebStorm detects that your code can be modified or improved, a light bulb icon appears on the current line in the editor: for intention actions and for quick-fixes. This PPA is developed and maintained by Marcel Kapfer and is available for Ubuntu 18.04, 16.04, 18.10, 19.04 and 16.04.If you managed to get here then I'm assuming you also have problems using Jetbrains tools with Windows Subsystem for Linux 2 (WSL2).
If you use Maven or Gradle, add a dependency with following coordinates to your build script:A set of icons used in JetBrains' web applications - GitHub - JetBrains/icons: A set of icons used in JetBrains' web applications Method 5: Install IntelliJ using PPA (valid for Ubuntu-based Linux distros) There is an unofficial PPA available that you can use to easily install IntelliJ in Linux Mint, elementary OS and other Ubuntu-based Linux distributions, including Ubuntu of course. This addon for FlatLaf bundles many popular open-source 3rd party themes from JetBrains Plugins Repository into a JAR and provides Java classes to use them. Open the executable file then follow the installation wizard. Then click on "Download Amazon Corretto 11" and look for "Windows 圆4" bit platform and download the executable. Search in your browser "Amazon Corretto" or go to their website using this link. Use the "New project from existing sources" to load the cloned code in IntelliJ. Might be that the c icon indicates a class. In IntelliJ I've had the icons not display when I had more than one class in a file (I'd placed the class-closing curly brace before the inner class).
