⁨2.1.66 - Card Not Revealing

[andre_angelo]

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 this card and see if there is a specific error with it? I’m not sure what it could be though.

I updated today to 2.1.66.

This happened twice today among 60 cards studied.
I can’t reproduce this intentionally, but it happened.

[cjdduarte]

It just happened again. I kept clicking on the screen and it appeared.

Hooray for the never-ending graphics driver bugs.

Please open cmd.exe and type the following

set QSG_INFO=1
cd \path\to\anki
anki

Replace \path\to\anki with the place you have Anki installed. Please paste the startup text you get here.

Then please try:

set QSG_RHI_BACKEND=opengl
anki

and

set QSG_RHI_BACKEND=vulkan
anki

and finally

set QT_OPENGL=software
anki

Do any of those help?

Replace \path\to\anki with the place you have Anki installed. Please paste the startup text you get here.

@dae, today I studied 140 cards and the error did not occur. I used OpenGL mode.
Did the logs above indicate any errors in this 2.1.66 version?

This didn’t happen until version 2.1.65.
