I updated the Classic theme just in case 🙂
Edit: can you copy and paste the list of plugins that you have installed here? Maybe we can figure out which one is causing the issue.
If you make new categories when you use the composer in those categories for posts, it appears blurred.
If you use the composer in posts on the originally made categories on Lavender , they are not blurred and appear clear.
Something I've noticed but not hugely bothered by I guess
The composer is also blurry in persona in some new categories as well.
noticed on post replies and new topics
