I am new to Java and I am having an issue with my eclipse SWT application once it is exported. It works fine as a runnable JAR on windows but when exported in the same manner on MAC I get the issue.

When I click on any buttons all my controls/buttons/dropdowns get replaced by a white box and some will only appear when clicked again individually.

Please help and if you need any further clarification please reach out.

Thanks in advance for you attention.
