Welcome to the 3.0 Bugs and Quirks Directory!
This directory contains information AS OF THE RELEASE OF SCRATCH 3.0. Scratch 2.0 and Scratch 1.4 are not covered here.
There are three different sections:

• Unfixed Bugs/Quirks. This is the section you expected when you opened this topic. All of the UNFIXED bugs (unintentional programming errors that impact the user in a negative way) as well as the quirks (intentional features that unknowingly impact the user in a negative way) are in this section.
  
• Fixed Bugs/Quirks. This is a log of the bugs on this list that the Scratch Team has FIXED.
  
• New Features. This section is a list of new additions in 3.0.
  

As you read this, keep in mind that the Scratch Team is NOT trying to ruin Scratch. They plan on adding back all of the old features and fixing all of the bugs, but, as it is with anything, this will take some time. @ceebee's post gives more detailed information.

! = Critical Issue

UNFIXED BUGS/QUIRKS:
Website
This section does not have any content right now.

Player/Project Page
! Scratch 3.0 uses WAY TOO MUCH RAM TO LOAD. For many projects (even those under 20 MB), it takes 2.6 GB or more during the loading process, but much less during runtime. Most mobile devices have about 2 GB of RAM in total.
! The page is non-responsive to browser size once loaded. This means that fullscreen toggle, device rotation, and other display changes are not reflected in the page, and therefore messes up formatting
! Some projects crash while loading on the project page. Possible causes include project size over 20 MB, sound effects being applied to longer sounds, and heavy use of the vector erase tool.
! Sometimes cloud variables randomly reset to 0, even when the project is not running
! Anti-aliasing does not occur when sprites are at 100% size
- Project page layout on mobile is broken (the player extends out into blue space)
- Sometimes fonts/images do not load on mobile
- The thumbnail on most projects does not appear on the project page after initial load
- When switching tabs, the project pauses
- If a costume has only one line, the line does not show (even if the costume has other content)
- Bitmaps uploaded as vector files are clipped
- The “touching?” block sometimes gives inconsistent and incorrect results with bitmap images. This can also occur while switching from normal view to fullscreen and vice versa.
- “broadcast and wait” blocks mess up some 2.0 projects because of the newfound lag with some blocks in 3.0
- When more than one sound is playing at once, the background sound(s) is garbled (apparently happens with Firefox volume set issue)
- There is a short pause after “play sound until done” blocks, making music loops problematic
- Tags are gone (not sure if the # method really works or not)
- Embed option is gone

Scratch Desktop
! .sb3 files cannot be opened by clicking on them; you have to open Scratch Desktop and select “Load from your computer”
! The program hasn't gotten any patches/updates since its release (unlike the web version)
- “Upload to scratch.mit.edu” feature is missing
- The project name is not shown or editable

Code Editor
! There is no way to see mouse x and mouse y at a glance. This is an important feature, not only for experienced developers but also to help new Scratchers figure out the coordinate system.
! When duplicating blocks, the action to place them (clicking) is the same action as running the script, causing unintentional script activation
! Block help is gone. Some people need help with blocks!
! The dropdown to change operator on operator blocks is not there (for example, > to = to <, + to - to * to /, etc.). It was very helpful! Now I have to disassemble my entire formula, substitute one little thing, and reassemble it again.
- Lists with long entries/certain characters are not interpreted correctly
- Lists with a very large amount of items run processes incompletely
- In projects from 2.0, uppercase letters in broadcast names are now lowercase
- After autosave, undo and redo are cleared (both in the code and paint editor)
- Define option in custom blocks is not there (I know it seemed pointless, but it was a nice shortcut to jump to block definitions)
- The min-height value for the editor is set too high (640-pixel-height displays show a scroll bar)
- Block text is blurry while scrolling
- Record/export video is gone
- The sprite icons are too small to see (especially on iPad)
- The sprite info area is larger than it needs to be
- Block padding is still a bit too much for some people

Costume Editor
! Costumes from the backpack are shifted and distorted. I'm not sure exactly what's going on, but it may be trying to center the costume when taken out of the backpack.
- The editor does not scale to the user's resolution
- In the costume selection sidebar, the last costume icon is partially covered by the New Costume button if there are enough costumes to fill the vertical height of the screen.
- Spacing of text from 2.0 is broken due to the new fonts and their respective spacing
- Some gradients in 2.0 projects have been flipped
- Fill bucket no longer works on outlines
- Outlines on the Scratch font are very, very broken
- Resize points aren't visible or draggable outside of the costume border
- Smooth button is gone
- When using the reshape tool, sometimes clicking on a point creates a new point
- Pencil tool (line tool with easily-defined shape) is gone
- Color selection sometimes resets to the default purple
- Color table (very convenient) is gone
- Centering tool in the paint editor is also gone

Sound Editor
- When duplicating sounds, the sound is slightly warped
- Sound trimming is restricted to beginning/end
- Sound trimming always starts a bit into the beginning and end of the sound
- Sound trimming always leaves a short pause at the end (both visibly and audibly)
- Select/copy/paste is no longer available in the sound editor

FIXED BUGS/QUIRKS:
- Blurry player graphics have been improved
- Instructions/Notes and Credits sections now save correctly
- Hiding of empty Notes and Credits/Instructions sections happens again
- Favorites/loves are now showing in Messages
- Saving no longer freezes the page
- This project used to not load (but it still existed, because I could run it in Phosphorus, 2.0 restore tool, etc.) It does now!
- Project to project (they both run on the same engine with few changes): This project worked perfectly fine, way better than in 2.0, but this project was completely broken (y-acceleration is broken, extreme lag, etc.) Note that before the update, both projects worked at a similar level of lagginess and functionality. I believe this was due to

broadcast [ v] and wait

blocks having to wait longer due to 3.0 lag.
- Cloud data history has been added back
- Changing variable dropdown (in projects with lots of variables), which used to be cut off at the top of the page, has a scrollbar now
- Converting from bitmap to vector (and vice versa) has been greatly improved
- Export costume option has been added back
- GIFs can be uploaded again
- Sliders have been restored to their original min/maxes on 2.0 projects, even the ones that have already converted to 3.0!
- Autosaving has been greatly improved
- “set slider min and max” has been restored as “set slider range”
- Uploading projects now replaces the contents of the current project
- The “touching color?” block now matches the precision of Scratch 2.0
- (unconfirmed) Fixes to crashing on the project page

Please credit those hard-working people in the Scratch Team for fixing all of this in just 2 months!

NEW FEATURES
- No more Flash (browsers are starting to stop supporting this)
- The editor has a new, modern look
- The brush tool (like the pencil tool, but can also be used for cut-outs with the reshape tool)
- Sound effects
- Undo and redo
- Mobile functionality
- New vertical clean up method
- Code menu is one list and slightly transparent
- Many more extensions
- More costumes and sounds
- Bitmaps uploaded as vector files are editable glitch-free
- Bitmaps are uploaded in higher resolution

- My display is 768 pixels in height. The 3.0 editor displays at 640 pixels of height. Firefox (with no menu bar, default density, and bookmarks bar showing) combined with the Windows 10 toolbar (default density and no autohide) makes a scroll bar appear for vertical scrolling. It's a very small amount, but annoying nevertheless. So I'm guessing that the calculations for page height are slightly off.

I had this issue when teaching in school yesterday on a low res 768 height display - pressing F11 to go full screen got rid of the scroll-bars.

not a fix but I think its a workaround (as long as just using Scratch - pain in the neck if wanting to quickly switch to other browser tabs of course)

I actually was going to post about the new vertical clean up, because I don't like it and thought it was a glitch.

The ability of relocating the center of a sprite is also gone it seems

Volume bug. It was later researched to come from a Firefox quirk.

Thanks guys! Added to the OP.

I'm going to keep bumping until the ST sees this.

I think that if you want to draw attention to a bug that you've found that no-one else has reported then it would be better to make one post/bug.

But check first that the bug has being previously reported and isn't on the known list that Scratch team are working on

That would take a very long time with all of the bugs I need to report.

Heya fellow Scratchers!

I don't know if this same problem happens to you, but there is a bug where I can't put things from my backpack into my project. Are other people experiencing this? Is there a way to fix this? Please respond asap! I wanna make a project, but can't due to my backpack confusion

'Til next time, Music-Addict

'Til next time, Music-Addict

There have been lots of reports of bugs with the backpack and Scratch team are working hard to fix them
BTW If you experience, any bugs or glitches, you are better off making your own new post

Please can you add this bug to your list, the official list hasn't been updated for over a week and nobody from Scratch Team seem to have acknowledged it.

Sure! Added.
To be honest, I don't think I'm going to have any more luck than you are, but it's worth a shot.

The SVE keeps stretching the costumes for no reason, and it is utterly annoying.

Can you share a simple project that has this problem?

Where is the the button to record a project video? It seems disappeared.

If I define e new Block, the block is NOT visible from alla the sprite. It is a Bug. Please correct.
