Ever since the appearance of Night Mode, certain images have not displayed for me, either on the desktop version or the iOS version of Anki. For the most part these are .svg images which default to saving as .png on macOS. Examples would be images like those on the Wikipedia page for 人, like this one:
When I view an image like this in Anki in Night Mode, the lines remain black, but the background also becomes black, and the Anki window is black: so it becomes invisible. (Actually, on Anki desktop on macOS the window background isn’t as black as the lines, so you can still faintly see something. But on iOS, I can’t see anything at all.)
I guess one workaround would be “don’t save .svg as .png, duh!” Other images I have don’t suffer from this problem. But that would still leave me with a lot of images in cards created pre-Night Mode that would have to be replaced.
I’m using Anki desktop version 2.1.42 (8eebfe18) for macOS, and 2.0.72 (20072.3) on iOS. I’m using the built-in Night Mode, not an add-on.
Is there something in the Anki settings that I’m not seeing that could make these images visible? More generally, what is it about these particular .png images that causes this behavior?
Any suggestions would be greatly appreciated.
