Why are Swing Components Rendering Differently in IntelliJ IDEA Between JDK 1.8 and JDK 1.7?

Swing Rendering Inconsistencies Between JDK 1.8 and JDK 1.7

Issue:

After upgrading to JDK 1.8, users encounter distorted Swing rendering in IntelliJ IDEA. Fonts are misaligned, and button labels disappear upon mouse hover. This issue persists despite updating drivers and other system components.

Potential Solution:

To address this rendering discrepancy, consider the following solution:

Disable the use of Direct3D in Java's 2D system by setting the "J2D_D3D" environment variable to "false." It is recommended to create an environmental variable with this name and value without quotes.

Implementation:

// Set System Environmental Variable "J2D_D3D" to Disable Direct3D
System.setProperty("J2D_D3D", "false");

Additional Considerations:

• Restart any Swing applications after making this configuration change.
• Please not that this solution might not work for all users. If the issue persists, it is advisable to investigate additional potential causes.

Discussion:

Direct3D is a Microsoft technology that provides graphics accelerated rendering. While it can improve performance for certain applications, it may lead to rendering issues in Java Swing applications under certain conditions. By disabling Direct3D usage, we can revert to the default rendering mechanism, which may resolve the inconsistency between JDK 1.8 and JDK 1.7.
