A nonsense format comes up when I hit on the list of Physics a question to look at it. Colors and bubbles and distracting fuss. Help please. It happened after I rejected and edit by xray0, but it could be a coinidence. ( for many of the corrections I do not see a difference, for some there is grammar capitals or something)
Don't worry, it''s just an April Fools Day gimmick. You can toggle it off & on with the Clock icon in tbe top bar.
The Clock icon is supposed to disable / enable it on all pages, but it's slightly buggy, and the devs are working on it. In the mean time, if you use the mobile view you'll see a boring normal display. (The "mobile" button is at the bottom of every page).
Update The bug is now fixed.
Thanks everybody for the comments. The format returned to normal when clicking on the clock image on the top line. It is on the right side of the top line.
