Display Issues on Linux
Hardware acceleration defaults to off on Linux. Enabling it in the preferences screen and restarting Anki may make Anki’s interface more responsive, but some users may experience missing menubars, blank windows or crashes when it is enabled.
You can adjust the display driver in Anki's Preferences screen. We recommend you try both settings, and see which one works best for you.
If you're unable to open Anki, you can adjust the driver in a terminal,
by writing either auto or software into
~/.local/share/Anki2/gldriver. Please note that if
you’re using nouveau, it is known to be buggy, and it only supports
software mode.
