any information about this problem? I haven’t been able to write an article for days

Have you tried to clear your browser cache/cookies and try again?

I also tried in incognito from two different PCs

The line should only appear when dragging a card and it shouldn’t get stuck :confused: If it happens again can you check the Console tab of your browser’s developer tools to see if there are any errors?

If you do get stuck like that pressing Escape should clear the broken drag/drop state.
