thanks for the answer. I can´t get it to work with qt6. with qt5 at least the buttons work in the upper taskbar but with qt6 the programm seems to crash already on startup. I can´t click or do anything.

Hardware acceleration defaults to on. If you experience blank screens or display issues, you can try enabling software rendering using the terminal:
echo software > ~/.local/share/Anki2/gldriver6
If you wish to switch back to the default, change software to auto, or remove that file.
