Hello everyone!

We are now 8 months out from the launch of Scratch 3.0. As you may have noticed, the Scratch Team has not been super active on this thread (which was created in January 2019) and most of the bugs on this list are pretty much resolved.

That said, we are now going to close this thread. If you still have a bug or problem, please keep using the Bugs & Glitches Forum and we will try our best to look at your issues.

Thank you so much for your helpful feedback, thoughtful critique, and enthusiasm

Scratch on!

If any of these issue is affecting one of your projects, it would greatly help us if you shared:
- The project URL
- What browser and operating system you are using (e.g. Chrome on Mac)


I can’t add new assets to my backpack.
as of 1/04/19
Scratchers are not able to load things out of their backpack more than once, or not at all. Some Scratchers are reporting “Error Loading Backpack.”
This issue is one of our critical issues to fix. It is logged, and we are working hard on it!

I can’t load projects on the project page.
as of 1/08/19



When viewing projects on the project page, the stage appears as a blue error screen.
This has been logged and we are paying attention to the problem.

Many of these issues we were able to connect to various Chrome extensions that would block the project page and editor from loading. We’ve made some changes that have greatly reduced the number of these errors.

Some of these errors are due to incompatible browsers. If you are using anything below these version numbers, we recommend you update or try a different browser:

• Chrome (63+)

• Mobile Chrome (62+)

• Edge (15+)

• Firefox (57+)

• Safari (11+)

• Mobile Safari (11+)

Cloud variables are getting changed or reset.
as of 1/28/19
Scratchers are reporting that other people are able to change their cloud variables, or that cloud variables are broken. We don't yet know why this is but if this is affecting you, you can help share the following:
- Your project ID's
- When did this first happen?
- How often/how quickly did this happen? (example: I noticed the cloud var was reset an hour after I shared.)

Project thumbnail is wrong.
Some Scratchers are seeing the default Scratch Cat thumbnail invading their project thumbnails. Their project should instead be showing an accurate thumbnail of the actual project sprites. If this is affecting you, can you please share the project ID?


I’m not able to save my project.
as of 1/08/19
Many people have reported problems saving in the editor. If you are having trouble saving right now, it’s possible that our servers are down temporarily. It might also be because you recently uploaded or edited audio files. Sorry that you are having trouble! We are doing our best to address this urgent issue quickly.

What should I do for now?
What you can do to not lose your work is to click “File > Save to your computer” in the editor. Make sure you keep track of where it saves to on your computer.
When you are ready to keep working on it, you can upload it using “File > Load from your computer.” Hope that helps!

I’m having trouble with recorded/uploaded sounds.
as of 1/09/19
Recorded, uploaded, and edited audio files are causing a number of problems, including:

• preventing Scratch from saving

• crashing the editor

• producing glitchy or garbled sound

• not uploading properly into or out of backpack

• being unresponsive or freezing Scratch when you try to trim sounds

These issues seem related to the audio file being too big. We've noticed these problems in the web editor and also in the Desktop editor. We are hoping to fix this soon!

The editor freezes or lags randomly.
as of 1/08/19
Some Scratchers have reported intermittent freezing in the editor. This is most likely happening when the project periodically auto-saves. We're aware of this and hope to work on a fix soon!

Using the Bitmap Color Picker crashes Scratch.
Added 1/09/2019. We don't yet have a fix for this.

The eraser is not working correctly.
Added 1/09/2019. When erasing, the erased area has a fill or outline. We don't yet have a fix for this.

Here are some of the top requested features that were in 2.0, and are no longer in 3.0. Because they're not bugs, we probably won't fix them immediately, but rest assured we are thinking about them and plan to address them in the future

It's difficult to center sprites without the 2.0 crosshair tool.
We hear you on this. This is a very popular ask as well! We're invested in trying to make centering things easier in the future, though we might not get to it right away.

(fixed 1/03/2019!)
The Notes & Credits and Instructions sections take up space even if they are empty.
Before, when projects had either blank Instructions or blank Notes & Credits, the empty section would collapse so you could read the other section more easily. This bug was fixed on 1/03/2019.

(fixed 1/07/2019!)
Loves or favorites aren't showing up in Messages or “What I've Been Doing.”
This is a bug, not something we changed intentionally. We’re aware of this issue and we are working on it!

(fixed 1/04/19)
Project sprites are loading blurry in the stage.
Images look low quality, blurry, foggy, or pixelated. Some people are noticing this particular when they full screen the stage, or they are noticing it on specific computers. People have also noted that this is affecting vector (svg) assets more.
We have made fixes to this, but if you see any other weirdness, please note it here and share what browser you are using. Thanks!

(fixed 1/31/19!! So exciting!)
Lists and variable monitors are covering the nav bar.
When on the project page, some people are seeing monitors on top of the
nav, making it impossible/inconvenient to click on nav links.

(fixed sometime in February!)
I can't export costumes/sounds from the editor.
There's a lot of demand for this 2.0 feature.

(added back around 2/14/19!)
I can't upload gifs as sprites.
In 2.0, you were able to upload gifs to use as sprites. We intend to have this back in the future, we just weren't able to have it for 3.0! Stay tuned.

(fixed sometime in Mar/April)
I could change the slider min/max in 2.0, but I can't in 3.0.
Right now the slider min/max values default to 0 and 100. Ideally, you should be able to change these values. We intend to fix this soon, stay tuned!

(fixed in April)
Loading a Scratch project file creates a new Scratch project.
This is especially troublesome when Scratchers want to work on a “backup” of a project which is already loved/favorited/viewed. We're not sure when we can fix this but it's definitely important to us. In the meantime, you can use the backpack to move assets back and forth. It's not ideal, we know! It might be the best work-around for the time being.

(fixed)
I can’t see my blocks, even though they are running.
as of 1/28/19
Some Scratchers have reported that block stacks are missing or invisible, even though the code appears to be run correctly in the project.
This is one of our top priorities. We are investigating this right now!

Hi, would this be classed as a glitch or just something wrong with my device?

I can't load sprites from my backpack for some reason. Do you know why? Could it be because they are from an older version of Scratch(Scratch 2.0)?

@JACsterandOlibob It looks you have zoomed out, or have a really wide screen resolution. It's unfortunate that the paint editor is so small, huh? I'm keeping track of different screen resolutions and I"ll make note of that. Do you know your screen resolution?

I don't know my screen resolution. I got a Chromebook for Christmas, and it's really cool. But do you know my screen resolution?

Never mind, you were talking to someone else.

Resolution is 1920*1080 and screen zoom is 100%. Have tried on several browsers and accounts. Bit of a shame the editor is that small as I mostly use scratch for artwork.

where are the set slider min and max option?
i right clicked the variable on stage, and i saw 3 options, then i clicked slider.
THEN, i right clicked again and found the same 3 options

where is it?

define variable problem

@RyGuy1107 I'm not sure, it sounds like the issue that other folks have been having. If you weren't able to do the steps to move things to your backpack here, then it's possible that the assets no longer exist Otherwise, if they are older assets but were moved to 3.0 backpack, then it is probably the common issue we've heard with 3.0 backpack. Sorry for any inconvenience, either way!

Thanks for the info. We've gotten feedback about how the paint editor is too small, you are not alone! I really hope we can improve this too, but it will take some time. Stay tuned.

I did follow the steps, I put my sprites in a project. But I had so many, so I only put my OC sprites. But when I tried creating a new project, it's wouldn't let me place them. Can you contact the Scratch team to fix this?

But I don't know how to!

when i try to view projects, its just a white screen. im not able to view anything for some strange reason. its been like this for the past 2 hours or so. is there a way to fix this?

I can save audio in ver 3 in ver 2 i cude

one of my games from scratch 2.0, when it turned to 3.0, it is really slow and glitchy.
I try to increase the speed, but it still is slow.
https://scratch.mit.edu/projects/273368968/

I don't know if this is just me or just certain projects, but ever since 3.0 was swapped for 2.0, all the projects I've played/watched have all been glitchy. Every. Single. One. No matter if the art was made in bitmap or vector, no matter how popular it was, no matter who it was made by, no matter if it was originally made in 2.0 or 3.0. Is there a way to fix this?

I was unable to load any project or even the base editor page. I am using Chrome on Safe Mode of a Windows computer. All I get is a literally blue screen.

I did, the error is when some scratchers try to add them back (including me) it will say “Error loading backpack.”
