On larger Java source files, the editor window becomes corrupted, as if components of the IDE and the text window are being drawn without first clearing the render buffer. This is on Kubuntu Intrepid running on an Intel CPU and Intel 915GM GPU; the desktop environment is KDE 4.2.1. Netbeans is 6.5.1, and Java is 1.6.0_10. I've also tried this with the JDK 1.7.0, but Netbeans ignores all mouse clicks with that VM and is therefore useless. Composite is enabled in X11. I've tried the -Dsun.java2d.d3d=false argument, and the J2D_D3D=false and AWT_TOOLKIT=MToolkit enviroment settings. I haven't seen any other Java app behave this way, including Eclipse (which uses an entirely different GUI toolkit and is therefore probably not really comparable). If the bug tracker allows, I'll attach screen shots. --- SER

I meant to also say that this corruption *only* occurs in the editor window. No other part of the Netbeans UI appears to be affected, including the console or other text-rendering windows. I've also only noticed the problem while editing Java files (I haven't tried other source files, but I have looked at large-ish plain text files), so it may be related to syntax highlighting.
