Color Themes

Noemi includes 3 color themes selectable from View > Theme:

• Dark - Default flat, minimal dark theme
• Light - Inverted for bright environments
• High Contrast - Accessibility-focused, maximum contrast ratios

Theme preference persists across sessions. All UI elements -- canvas, nodes, editor panels, mixer, modulation matrix, transport, dialogs -- respond to theme changes, including switching while a project is open.

UI SCALE

View > UI Scale lets you resize the entire interface from 50% to 200%. This is useful for high-DPI displays or when you want to see more of the canvas at once. The setting is saved per session.

LINUX GRAPHICS

On Linux, the standalone app uses GPU-accelerated (OpenGL) rendering when a compositor is detected. Desktops without a compositor (i3, dwm, and other bare window managers) automatically fall back to software rendering, which avoids a freeze at launch on those setups. Plugin builds always use software rendering.

View > GPU Rendering lets you override the automatic choice (Auto / On / Off); changes take effect on the next launch. The setting is stored in ~/.config/Noemi/preferences.xml as openGLMode (0 = auto, 1 = on, 2 = off), which can be edited by hand if the app will not start. Setting the environment variable NOEMI_NO_OPENGL=1 always disables GPU rendering, for both the standalone app and plugins (launch your host with the variable set).
