⁨2.1.66 - Card Not Revealing

On version 2.1.66 of Anki (just installed today), I’m having an error revealing cards. I can recreate it frequently, but I’m not sure what’s exactly triggering it. It happens with multiple cards, though not always the same ones. (video) When I click my deck and open the first card, I hit spacebar to reveal the answer, but it does not show. I wait to see if it loads, but nothing happens. If I click and drag downward from the question, it is revealed. @dae Maybe you could check out…

The next release will have an option to change the video driver in the preferences.
