Java Swing Not Rendering Correctly -
i have been working on project. in 1 part of project needed draw on jpanel. graphics2d object passed model part of framework , model draw whatever needs draw @ instance. problem jframe not rendered correctly. looks half white shaded , not painting correctly. works fine on laptop (sony vaio, windows7) it's not rendering correctly in other systems tested (2 dell laptops,windows8;1 thoshiba,windows7;1 samsung, windows8). it's rendering correctly on few other systems teammate tested.
i'm sure there no errors made in model part. problem doesn't seem rendering on jpanel. 1 information can give we're doing our project in netbeans. perhaps code generated netbeans ide causing problem? checked code couldn't identify problem. it's difficult post sscce share screen shots of issue.
ok since don't have enough reputation post images see links below....

edit: days later problem occurs in system not worse. please refer images in comment.
i had same problem, changed display setting high performance , solved problem (in windows 8 , java 1.8).
