Additional context

I've encountered the exact same issue on my Arch Linux machine, also with earlier versions of the installer. My workaround is by installing Iris in a Windows virtual machine and then copying the files to the host computer, but this is a rather tedious and annoying process to do.

If someone needs it:

Kernel: 5.13.9-arch1-1
OS: Arch Linux
GPU: rtx2060
OpenJDK version:

java version "16.0.2" 2021-07-20
Java(TM) SE Runtime Environment (build 16.0.2+7-67)
Java HotSpot(TM) 64-Bit Server VM (build 16.0.2+7-67, mixed mode, sharing) 

Are there any errors in console?

Yes, that works perfectly!
So in the end you just need these two commands:

export _JAVA_AWT_WM_NONREPARENTING=1

java -jar Iris-Installer-2.0.0.jar

So my theory about this being a Linux issues and not an installer issues was correct, which well I'm not happy about, is nice to see

Yes, probably. I've added the export to my .bashrc file, I'll see if it affects other gui applications.

can confirm, works here as well. thank you Niko
