Bug 436559

Description Fredrik Attebrant 2014-06-04 07:11:15 EDT

Using Eclipse Luna 4.4RC2 on Windows 7.
Have a number of editors open (a mix of Java and XML).
Editing Java and maximizing the editor.
Sometimes, there's a glitch in the refresh causing the tabs at the top of the editor area to not be refreshed properly.

Checked the Error log and got:

eclipse.buildId=4.4.0.I20140522-1330
java.version=1.7.0_51
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US
Command-line arguments:  -os win32 -ws win32 -arch x86_64
