Been living with this for about a week and I've run out of ideas. Two things that I think are the same problem: When I pick a card up to move it, I don't get the usual tilted card following the cursor. I get a long thin vertical line. The drag still works - I can drop it where I want and it lands correctly - it's just that the thing I'm dragging has no width to it.
And the card titles now wrap onto a second line almost immediately, after two or three words, while the rest of the card sits there empty. The text isn't using anything like the full width available to it.
Alongside that, the lists have stopped being held to the window height. Each one runs as long as its contents so they all end at different heights, and the longest ones spill off the bottom of the screen with the final card cut through the middle of its text. No scrollbar inside the lists. The top nav bar has also gone flat grey instead of picking up the board background.
Putting those together, everything that should have a width or a height applied to it seems to have collapsed to nothing. Cards, card text, lists, the drag preview. Which makes me think one stylesheet isn't loading rather than four separate things being broken. Ruled out already, so nobody needs to suggest them: - hard reload, many times - service worker unregistered and site data cleared for trello.com - incognito - all extensions disabled - zoom back to 100% - Safari, identical Chrome on macOS.
Here's the bit I can't square. It follows me into incognito and into a completely different browser, which rules out anything cached locally, but the CSS everyone gets served should be the same. So either something is being blocked before it reaches me, or my account has been put into a different build of the board view to everyone else. Which is really my question: has anyone been rolled into a new board rendering experiment recently, and does this look like it? And if you've had the vertical line on drag specifically, I'd love to know what fixed it.
