Hi,
Sorry that you are seeing this issue with Darkest Dark. Thank you for the screenshot.
Can you please check how it looks in Eclipse Dark theme? Window > Preferences > General > Appearance > and select ‘Dark’ for theme.
If the problem is only with the DevStyle Dark theme, then please give us some more details :
1. Version of HANA Studio and the Eclipse version on which it is based on.
2. If you have installed HANA Tools on top of Eclipse, then please share the update site url.
Apologies for inconvenience caused.
