(my no distractions add-on is disabled, so it seems like the newer versions have a full-screen mode inbuilt, is that right?)
Also, the add-on sadly seems to not work with the newest 2.1.54 qt5 version. So let me know if anyone has a working add-on to recommend. I really used to like using this one, but I am not ready to downgrade to use it as I’ve learned to like what the new version has to offer. https://ankiweb.net/shared/info/1049863218
I think @cqg was pointing to the very last paragraph of that page, where it says you should change the video software option from opengl to whatever are your other options (in Anki’s settings).
