Description Stephan Herrmann

2011-04-29 12:52:58 EDT

This is a fresh install of Kubuntu 11.4 with
 - KDE 4.6.2
 - java version "1.6.0_22"
   OpenJDK Runtime Environment (IcedTea6 1.10.1) (6b22-1.10.1-0ubuntu1)
   OpenJDK Server VM (build 20.0-b11, mixed mode)
 - GTK exists in these versions:
   - 3.0.8
   - 2.24.4

On this system a freshly installed Eclipse 4.1 (I20110425-0200) has severe
drawing problems:

Initially all view toolbars are empty, buttons appear only when the mouse
moves over them (and stay visible from there on). The main toolbar is not
affected.

Once I start to create projects and files, views sporadically lose their
content (completely or partially). When placing the focus into a tree-based
view, it is painted correctly, but may disappear again when the view loses
the focus.
Text views ofter appear with partial content, i.e., some lines visible
others not. I've even observed partially garbled lines (in the console view).

Since this system has just been installed I hope that no weird configurations
of mine are the cause but the effect should be reproduceable on other
machines, too. However, an older installation with Kubuntu 10.4 and KDE 4.4.5
does not exhibit these issues.

Hi Stephan, thanks for testing Eclipse 4.1.

Are you on a 64-bit machine? Do your findings match the screenshots posted on bug 333965?

Yup, 64-bit machine but 32-bit OS and software.

Again: yes, looks pretty similar. Even more: the workaround using
  export GDK_NATIVE_WINDOWS=true
fixes the issue for me.

Closing as duplicate, but with a word on styling: all buttons now look ugly
with explicit square gray background on various surrounding backgrounds.
May be bad interaction with KDE styles from the environ simulated within GTK?
