Anki not starting

Hey there,

suddenly anki doesn't work on my arch installation anymore.
When I executed it on the terminal it told me segmentation fault.
I used dgb to debug it:

Re: Anki not starting

Apparently it only starts in a Wayland session, does anyone have an idea why that is the case or how one could find out?

Re: Anki not starting

Have you looked at the wiki page for anki?

Or the upstream website?

Re: Anki not starting

For anyone else having this problem (as I did), the wiki page and the upstream website do indeed have the solution, which is to change the hardware acceleration setting.
