[GTK4] weird toolbar icons on KDE

[danthe1st]

Describe the bug
When I open Eclipse 2026-09 M1 with the SWT_GTK4 environment variable set to 1, the toolbar icons are incorrect.

When I close the Welcome view, it looks like this:

This is what it looks like with Eclipse Platform:

I am also not able to right-click on the perspective icon on the top right.

To Reproduce

• Install Eclipse 2026-09 M1 (in this example, I used Eclipse IDE for Java Developers) from the installer
  • It also happened with the Platform Runtime Binary for Linux (x86 64‑bit) from https://download.eclipse.org/eclipse/downloads/drops4/S-4.41M1-202607031319/
• Start it with the environment variable SWT_GTK4=1 and open a workspace
• Observe the toolbar

Expected behavior
See screenshots

Workaround (or) Additional context

As suggested by akurtakov (#3420 (comment)), adding the GTK_THEME=Adwaita environment variable fixes the issue.

[akurtakov]

So broken toolbar icons are down arrows. Can you please start with GTK_THEME=Adwaita and report whether you see the same problems?

[danthe1st]

I can confirm that the toolbar works with GTK_THEME=Adwaita SWT_GTK4=1.

However, the other problems remain. I cannot right-click on the perspective button (i.e. the context menu doesn't load) and closing the welcome tab shows basically an empty pane:

Window > Show View > Project Explorer or Window > Perspective > Reset Perspective doesn't fix that either.

[akurtakov]

For the record, which theme was used in the broken case?
P.S. I concentrate on single/main issue per report and ignore the rest as otherwise issues become unmanageable and pure mess.

[danthe1st]

For the record, which theme was used in the broken case?

$ gsettings get org.gnome.desktop.interface gtk-theme
'Breeze'

The KDE theme I'm using (if it is relevant) is Kubuntu Light.

I concentrate on single/main issue per report and ignore the rest as otherwise issues become unmanageable and pure mess.

I will create another issue for that.
