-0.15000000 is the brightness value that's equivalent to the default one (0.50000000) when brightness levels are working properly. This can be verified in windowed mode where you cannot adjust brightness as the brightness section is removed from the options menu entirely or by taking screenshots while in fullscreen. I have added it to the fixbox about the issue in the page and moved all of it to the issues fixed section as well.
