Frame blurry when starting with bundled launcher

[ElijahSey]

I am trying to package a java desktop application with a gui. When i start it with the launcher, everything looks blurry: When i start the jar file directly using the bundled jre everything displays correctly:

My packr configuration file:

{
    "useZgcIfSupportedOs": true,
    "executable": "CardIdea",
    "mainclass": "presentation.CardIdea",
    "resources": []
}

The packr command:

java -jar packr-all-4.0.0.jar 
--platform windows64 
--jdk https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.8%2B7/OpenJDK17U-jre_x64_windows_hotspot_17.0.8_7.zip 
--classpath cardidea-0.1.0.jar  
--output cardidea packr-config.json
