I facing a problem like this. I am using Zorin OS and I have finished some projects on windows OS. Now, I want to import and recreate my projects in Zorin OS. I have already installed eclipse on Zorin OS and everything looks good except window builder. It works abnormally, like this image. How to fix this issue? I love eclipse because I can customize all codes generated. Are there any alternatives like eclipse IDE so that I can customize all codes? Please suggest me. Thanks.
