Using canvas images as backgrounds, I've noticed inconsistent behavior of visuals in High Contrast mode:
SVG Image Behavior: Unlike wallpaper images, which are removed and replaced with a black background in High Contrast mode, an SVG image (with white areas around the visuals) remains visible and is not overlaid with black.

Visual Backgrounds: When setting a white background on visuals, it gets removed in High Contrast mode. Some visuals (e.g., bar charts, pie charts) ignore the background and show the original canvas image instead, while others (e.g., new card visuals) turn black only in certain areas, not the entire visual. (title of the visual)
- What determines whether a visual’s background is removed or turned black in High Contrast mode?
- Is there a way to ensure consistent background behavior across all visuals?
Shapes as Workarounds: Adding white-filled shapes behind visuals to force a black background in High Contrast mode doesn’t work. Instead of turning black, the white shapes turn yellow, just like black text does, leading to yellow text on a yellow background.
- Why do white-filled shapes turn yellow instead of black in High Contrast mode?
How can be achieved a predictable High Contrast behavior when using custom backgrounds in Power BI?
