Unable to open JCEF browser in IntelliJ Tool Window on Linux

[JoaoSamoes]

Hello,

I am creating an IntelliJ plugin that uses your framework to show a site on a Tool Window, as you can see in the attachment.
This is working fine in Windows and MacOS, however in Ubuntu 20.04 and 22.04 it is not working, it shows "Nothing to show" (as you can also see in the attachment) and not even the browser is opened, which should at least do that.
Is there any issue with the Linux OS that I am not aware of?

Thank you

IntelliJ ships its own fork of JCEF. Have you tried the official api from jetbrains? https://plugins.jetbrains.com/docs/intellij/jcef.html

Hello @FriwiDev

I am already using it yes, however nothing works.
No logs either on this.

Thank you

As far as I am aware, there is no such issue under Linux. You could try if the sample app is running on your ubuntu system. If it does, then this is an issue that can only be worked on by jetbrains.
