Description Stephan Herrmann CLA 2011-06-02 07:16:32 EDT 
This is on Kubuntu 11.04:

All buttons are drawn with a square gray background.
See attachment 196843 [details] (originally from bug 333965 comment 48).

I am not aware of any custom settings that might have caused this.

At a closer look this already happens with Eclipse 3.7, just, given the
overall grayish L&F it doesn't hurt so much. But with the white looks
of 4.1 this becomes a pain.
Comment 1 Stephan Herrmann CLA 2011-06-03 19:08:25 EDT 
It seems the issue is caused by a specific widget style. The gray background
occurs when using this default KDE setting:

  Application Appearance : GTK+ Appearance : Widget style: oxygen-gtk

When I change this to "QtCurve" (not installed by default) the buttons
are correctly drawn with transparent background. Only during mouse-over
a button is raised and gets a gray background. This might be intended?

So using QtCurve is a viable workaround, but for Kubuntu oxygen-gtk is the
default and then Eclipse 4 looks broken.

For more, recent trouble with the default KDE-gtk theme see
http://www.eclipse.org/forums/index.php/t/441187/

Also bug 367603 happens with that theme, only.
Too bad that's the default theme in KDE...

Should we put up warning signs for Kubuntu users that we recommend to
install qtcurve before running Eclipse? A special readme for linux platform?

How is this issue with Luna? Many things changes including the default gtk version which has theming so different.

Almost 3 years passed without reply. Closing. Please reopen if it still happens with supported version.

In normal use and with OS/KDE versions 5 years older than in the original report, things are mostly good in this regard. Only the dark theme still suffers from part of the same issue. In the attachment you can see that buttons in different locations have the same background, which does not adjust to the actual background of the container widget.

But seing that the "GTK" theme (with underlying "Breeze") does not exhibit this problem this may well be a bug in the dark theme itself.
