Important Bugs:

  • The “Hi. Try out our new feature” tool-tip for the new “Set Thumbnail” button freezes the site. To fix it, press an arrow key or try out the new feature.
  • Sometimes when going to a comment from a link or messages, it takes forever to load, however you can:
    1. Go to the profile and find your comment.
    2. Hard reset Ctrl+F5 (Command+F5).
    3. Reload page a bunch of times.
    4. Delete browser history. (If you need to do this)
    5. Delete cookies and reload. (You will be signed out but sign back in) (if you need to do this)
    6. If it didn't work repeat the steps.

✏️ Editor Bugs:

  • Some reporters are aligned incorrectly. Lists are aligned to the left, and custom block boolean inputs are aligned to the right.

    Credits to AmpElectrecuted
  • When switching the rays backdrop to bitmap then back to vector, it crashes. source

  • There's a small gap between block dropdowns. source
  • When putting a reporter in a color input and undoing, the color input disappears. source

  • When putting nothing in the custom block, you get a half cut stack block.

  • This bug after choosing a sprite where it still shows the “choose a sprite” tooltip.

  • When you try to delete a sprite at the bottom, the pop-up goes off the screen.


⚙️ Technical Bugs:

  • Scratch's cloud variable monitor doesn't work, and neither do the variables themselves. This is because what clouddata.scratch.mit.edu (Scratch server link) is pointing to, there is still DNS but no ping.

    Terminal (credits to ampthescratcher):

    ampthescratcher@fedora:~$ ping clouddata.scratch.mit.edu
    ping: clouddata.scratch.mit.edu: No address associated with hostname
    ampthescratcher@fedora:~$ dig clouddata.scratch.mit.edu

  • You can go to any site in the post preview (the button), this is because it is an iframe (embed), which should be fixed.
  • Next function does not work on https://scratch.mit.edu/accounts/login/ when you log in with a next function (e.g. ?next=/mystuff/) it does not work.

✉️ Website Bugs:

  • 2.0 pages shows you have a new message but you don't. (Sometimes it shows the largest amount you got in that day) source
  • When putting the %15 symbol (Cube symbol: ) into a costume name, the editor column breaks.

    Credits to GvYoutube
  • Sometimes the 1st comment on your profile is older then the account. source
  • Sometimes signatures go too high and show the purple background. source

    Credits to alboxer2000
  • Sign in and join scratch hover background doesn't fit the navbar on 2.0 pages.

  • Scratch is indexing projects slowly. source
  • When ST merges a topic, it says the wrong OP. source


  • Sometimes project thumbnails break. source

    Credits to GratefulGamer9398233
  • When making a comment with an unsupported emoji, the error is broken. source

    Credits to alboxer2000
  • When deleting a studio, the alert is empty.

  • Sort by studio's Hosted by Me is forever stuck at empty.

  • Debug button in editor's hover background color width is too small.

  • Bad margin here.

  • When hovering over messages on 3.0 pages the unread messages counter doesn't expand with the icon.

  • Studios the Project is in counter in my stuff always shows 0.

  • On 3.0 pages scratch wiki would link to scratch-wiki.info, but on 2.0 pages it links to wiki.scratch.mit.edu.


  • Explore page doesn't locale to your language.

  • Last post will say the wrong last post. (take for example right now:

    the last post was not in 2021)
  • On 2.0 pages, when scratch is loading the page, at the bottom you still see “Adobe Flash Player is not supported”.
  • Sometimes when you comment, you comment twice, this may be due to the messages not loading bug or internet issues.

  • Some categories on the homepage do not show.
    ]
  • On 2.0 pages, you can hover over the logo from 2 pixels down, this is due to there being an <a> tag being that size. (80 x 48)

  • Some users made topics/posts but the counter says 0. source

  • Sort by remixes doesn't show all projects and is in the wrong order. source

QNA:

Q: Why doesn't my backpack load when I put stuff inside of it?
❗️ A: The backpack has a file limit, try deleting things.

Q: Why doesn't my thing save in the editor?

Q: How do I report bugs?
❗️ A: A bug description, when it started, where it is, a link (if it's in a specific project, please link to it), reproduction steps, expected result, actual result, operating system, browser and Flash version (should be already there. if not, click the globe icon in the tools bar above the topic itself), screenshot.

So on the top bar of the editor, the share button and the project name and see inside is condensed due to the debug button.
this seems to be in the process of being fixed according to a PR

you need to add that the new scratcher to scratcher slideshow does not work - in the new scratcher to scratcher slideshow, you are taken to a slideshow of the community guidelines where you get stuck on the “Scratchers treat everyone with respect.” section but can't progress.

this bug means no new scratchers at the moment can become scratchers.

It's still a bug as it's not supposed to be invisible.

Depending on your screen size the sprite deletion confirmation may go off the screen and you may have to zoom out to see the buttons. I'll see if I can replicate this and give an image. (Might take a while because the bug first happened on my school Chromebook and I'm on Christmas break.)

Not just that, but cloud variables in general are broken. Try going onto blockbit or one of griffpatch's cloud projects. It will not work.

Firefox has worse performance when running scratch projects, however, you can always try fixing NextDNS. source
this is due to firefox using spidermonkey js interpreter instead of v8 iirc
