wayland/sh1106g-oled-i2c/invert-display
Enable or disable display invert mode (white-on-black vs black-on-white). This has an immediate effect on the display, no need to use the send-buffer-to-display node -- buffer contents are not changed, rather a different pixel mode of the display hardware is used. When
enabled, drawing BLACK (value 0) pixels will actually draw white, WHITE (value 1) will draw black.
