Theme drop down greyed out

JoseVidal · ‎2025-06-09

HI,
I'm using: windows 11, STCubeIde 1.18.1 on a fresh installation
I tried to:

Open org.eclipse.ui.workbench.prefs: everything here was comment out, I added a line "themeid=org.eclipse.e4.ui.css.theme.e4_dark"
Manually Deleted .metadata
Searched CubeIDE plugins/ directory for *theme: found only "org.eclipse.e4.ui.css.swt.theme"
Tried running stm32cubeide.exe -clean
Tried to install a theme plugin from market place, pointless as I can not select it from drop down after the installation
Restart windows
Reinstall STcubeide

Any ideas?

First let me thank you for posting.

This misbehavior is linked to ECLIPSE which is the base of the STM32CubeIDE.
I advise you to address to the ECLIPSE community for info.

BR,
