@vaporeon_ that looks like the high contrast theme to me; the standard dark theme uses a less dark background color
re: no image descriptions
@aescling The background colours look the same for me in your two screenshots (and brighter than on my computer?), but at least the buttons are less grey and easier to see in the "high-constrast" version (why isn't that the default? who benefits from grey buttons that are hard to see?)
@aescling Oh? Can I have screenshot?
Looks like what I want is an even-higher-contrast theme...
