Known issues with Anki 2.1

Hardware acceleration and startup issues

The Windows and Linux builds default to software rendering, due to issues with hardware acceleration on some computers. If you have a modern system, you can optionally enable hardware acceleration in the preferences screen, which may result in a performance improvement.

If Anki shows an error message on startup on Windows and restarting it a few times does not help, you can manually change the video driver by running the following in cmd.exe:

echo auto > %APPDATA%\Anki2\gldriver

If that does not help, please replace auto with angle and try start Anki again.

Shortcuts on macOS

The toolkit Anki uses does not currently support some shortcuts like cmd+left/right or cmd+delete when editing cards. Fn+left/right does work instead. You can also use a third party tool like BetterTouchTool or Karabiner to intercept the cmd+left/right keystroke when you type it into Anki, and have it automatically be rewritten to use the function key instead.

Undo shortcut

The undo shortcut has changed due to an issue with the toolkit. The new shortcut is visible when clicking on the Edit menu. If the toolkit fixes the issue in the future, the shortcut will be changed back.

Copy & paste problems on Windows

If you are experiencing problems with copying and pasting on Windows, please check if you are running other programs on your computer that monitor the clipboard, such as dictionary programs, clipboard managers or clipping tools. The toolkit Anki uses can have trouble when such programs are running.

Fcitx on Linux

Currently the Fcitx input method is not supported by the packaged version of Anki. On some systems you may be able to link in your system libray, but if that does not work, the only option at the moment is to switch to using IBUS instead of Fcitx.

Text size

If you find the text is the wrong size, there are two environmental variables you can try:

  • ANKI_NOHIGHDPI=1 will turn off some of Qt’s high dpi support

  • ANKI_WEBSCALE=1 will alter the scale of Anki’s web views (like the deck list, study screen, etc), while leaving interface elements like the menu bar alone. Replace 1 with the desired scale, such as 1.5 or 2.

On Windows you can add these to a batch file to make it easier to start Anki. For example, create a file called startanki.bat on your desktop with the following text:

"C:\Program Files (x86)\Anki\anki"

After saving, you can double click on the file to start Anki with that setting.

SSL errors

Some work and school networks intercept your internet traffic, and this can cause errors when syncing and downloading add-ons. You can prevent the errors from occurring by setting the environmental variable "ANKI_NOVERIFYSSL" to "1".

When you enable this option, you are telling Anki not to verify that it is actually talking with AnkiWeb. This means that not only your work or school, but also a bad actor on the local network may be able to intercept your syncing traffic.
