Odd display colors when using black background.

When I use black background for the watch face, it sometimes happens, that the colors of the display get odd (seems like inverted). Some of the displays are even not visible at all (music player widget).

Usually the first and last option in a menu is not visible properly but the rest is okay.

When I use the white background for the watch face, the issue usually disappears.

Please see the attached pictures.

Anybody seeing the same issues?

Happening on my FR945 bundle edition (RevD).
