Qt rendering bug in check boxes

Anki Help
1

Hi, I’m having an issue with check boxes in Anki on Windows 11.

When I try to check options (like in the Export window), the boxes don’t show a proper checkmark — they just get a highlight/border showing highlight instead of tick. If I click another checkbox, the first one unchecks/disappears. Basically, only one option can be “highlighted” at a time. this happens everwhere in the app where there are check boxes.

.

Things I’ve tried:

  • Restarting Anki

  • Safe mode (no add-ons)

  • Switching video driver in preferences

  • Switching between light and dark themes

  • Reinstalling the latest version (25.07.5 )

Nothing helped.

System info:

  • Anki 25.07.5 (7172b2d2)

  • Windows 11

  • Python 3.13.5 / Qt 6.9.1

Anyone else run into this, or is it just me?

I don’t have this issue on 25.07.5 (7172b2d2)⁩, debian trixie.

You can try the latest version, which might have fixed your issue already: Release 25.07.5 · ankitects/anki · GitHub.

Sorry it was just a typo I’m actually on the latest version 25.07.5 (7172b2d2) I even tried reinstalling it and the 25.08b5 pre-release, nothing worked.

Chatgpt said it’s a Qt6 rendering problem.

This looks similar to an issue we had in the past:

Does your Windows username/folder contain any characters other than A-Z?

5

Yes my username contains an apostrophe (‘)

  • I’ve tried replacing that theme.py file mentioned in your fix ,I couldn’t find it in Anki installation files.

  • I’ve tried reinstalling it in another path nothing worked

Thank you, a fix will be in the next beta/rc. Until that’s ready, the fastest workaround is probably to revert to 25.02.7 and install it in a folder that contains no apostrophes in its name or its parent names.

Thank you for your response I’ll be looking forward to it if not I’ll try reinstalling windows with another username.

You don’t have to. You can just create a new user and move your data from the old user to the new one.

Thank you I’ll try that later.

finally it’s fixed on the latest version 25.09, thank you for your effort.
