Created attachment 102054 [details] gif file of a broken section of the tab header Happens when there are more tabs than fit in screen width. When switching with [Ctrl+Tab] between tabs to a file with a tab that is not currently in view. If one tab is shown right, and I use [Ctrl+Tab] to switch to another file whose tab is not shown at this stage, then the current tab is removed and below it two other split-in-half tabs (as in the attached gif file) are shown below it, but the new tab of the new file is not shown. If I switch to another application, away from NetBeans and then back to it, then the tabs are refreshed correctly. Also if I move the mouse pointer over the tabs, then the tabs refresh correctly. The file type of the files I am switching is all java, and I don't have any windows open that are associated with them eg navigator, palette. It reproduces always on my computer. This is annoying because when using svn version control, the file names are difficult to see on the list of [Ctrl+Tab] (dark blue on black), so it is even more important I need to see the name of the current file in the tab.
pls provide jdk and nb version info, thanks
java version "1.6.0_21" Java(TM) SE Runtime Environment (build 1.6.0_21-b07) Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing) Product Version: NetBeans IDE 6.9 (Build 201006101454) Java: 1.6.0_21; Java HotSpot(TM) Client VM 17.0-b17 System: Windows 2000 version 5.0 running on x86; Cp1252; en_NZ (nb) Userdir: C:\Documents and Settings\Administrator\.netbeans\6.9

Created attachment 102505 [details] New gif file of a brokeen section of the tab header Between my first report and this update, I have: - changed my graphics hardware - changed my graphics driver - installed a new version of NetBeans netbeans-trunk-nightly-201010190000-javase-windows.exe The error reproduces as easily as before. These are the steps I do to reproduce the problem: Install netbeans-trunk-nightly-201010190000-javase-windows.exe Do not import settings Set full screen Turn off the editor toolbar Turn off line numbers Turn off diff sidebar Minimize all other windows eg Project window so the editor is the only window. Resolution is 1280 * 1024; font size large fonts 125% normal size (120 dpi) Create a simple example project: Menu|File|New Project|Samples|Java|GUI Form Examples Edit all files: Antenna ContactEditor Find JCheckBox JButton JLabel JTextField JTextComponent JComponent Component ImageObserver MenuContainer Serializable You might need to swap to files that are not shown in the tabs for quite a few times, but in my case, At the first switch to a file that is is not shown on tabs, the tabs are not completely re-rendered as shown in the attached new image. I guess the effect is easier to reproduce with lower screen resolutions. So please try to set your screen resolution to 800 * 600 to get a better chance to reproduce and fix the problem.
is this reproducible also when using metal or nimbus l&f?
How do I change the L&F of NetBeans itself?
use either --laf Metal or --laf Nimbus command line params
Created attachment 102540 [details] Test result with Nimbus L&F Thanks. Reproduces with different L&F, too.
Could this be target for 7.1 please? It still reproduces on 7.01. Quite annoying not to see what the file is that I am editing. Meanwhile I have new graphics hardware.
Still cannot reproduce in Product Version: NetBeans IDE Dev (Build 20130605-078e57e108d0) Java: 1.7.0_21; Java HotSpot(TM) 64-Bit Server VM 23.21-b01 Runtime: Java(TM) SE Runtime Environment 1.7.0_21-b11
Thanks. Meanwhile I have a faster PC, and I cannot reproduce this anymore, either.
