Blank screen after upgrade to Ubuntu 21.10

I upgraded to Ubuntu 21.10 and Anki simply shows a blank screen. When I start Anki from a terminal, I get this error message:

Qt info: Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

I tried setting this variable, I tried other variables that other posts encouraged me to try, I reinstalled, I tried logging out and back in without Wayland, I tried it all with and without hardware acceleration. What more can I try?

Perhaps it’s the same issue as this one?

Yes - thank you! That fixed it.

And, today, something in Ubuntu 21.10 seems to have updated and now Anki is again working without this workaround. Thank you for your work on this great program!

Looks like they decided to revert the breakage for now: Comment #36 : Bug #1944468 : Bugs : glibc package : Ubuntu

Hopefully we’ll have a new toolkit version available by the time they introduce it again
