New Linux version requires I launch it as "QT_XCB_GL_INTEGRATION=none anki"

I was prompted to install the latest version of anki, which resulted in a window like this. I tried 10 different things, but it seems I now have to launch it from the terminal as “QT_XCB_GL_INTEGRATION=none anki”.

AI is telling me this error might be important to include in a bug report:

System details:

So it worked before you updated your linux distro? Maybe you just need to choose a different video driver. Or maybe you are missing some dependencies in the updated version, though that would be odd (the package manager should have handeled that).

I know this is late, but I never updated my Linux distro. Its the most up-to-date. I was just reporting a bug. Whatever combination of versions don’t match on my system. I understand that being on Linux I’m not prioritized, but I thought that by providing the technical details of my failure, developers might be more easily able to take into account why their changes don’t universally work.

Oh, I see. In your title you wrote “New Linux version” which I evidently misinterpreted.

What do you mean? Anki works for linux for a very long time and has fixed linux specific bugs at least as regularily as bugs for other OSes.

I use Anki myself (on debian linux) on multiple devices (and VMs). If I had issues or opened PRs specifically for linux, it always had been answered well and welcomed.

Thank you. However, more info is needed.

  1. What are the “10 different things” you tried?
  2. Did you try everything on the troubleshooting list?
  3. From which version did you upgrade?
  4. What exactly changed before your issue occured? E.g. was the only thing that changed the Anki version?
