This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
When opening a big file (e.g. autogenerated antlr 260k grammar parser), which contain some errors, that netbeans can notice and highlight, text in editor renders with terrible artefacts. They seem to be copies of some screen areas (look at the screenshot). Attached file is correct, but files, needed by it are not available, so netbeans reports huge amount of errors. But one or two errors is enough to represent this bug. Short files are displayed correctly in any case. Additional info: Product Version: NetBeans IDE 6.7 (Build 200906241340) Java: 1.6.0_0; OpenJDK Client VM 14.0-b15 System: Linux version 2.6.30-ARCH running on i386; UTF-8; en_US (nb)
