I am creating this because I am sure there are going to be a flood of bug reports, as a rewrite of the blocks interface has just been released. This list is specifically focusing on the blocks, not any other part of the editor.

This is a living document (for a lack of a better term); please suggest bugs to be added to this list. I used https://github.com/scratchfoundation/scratch-editor/issues/533 as a source for some of these. @redspacecat listed some more bugs — thanks to them!

Bugs:
Editing Bugs:

• Broadcast block may cause a costume to disappear on a sprite. (Missing link because I pasted the wrong thing, whoops!)
  
• A broadcast block's dropdown becomes blank after importing a sprite and switching away. (Forum Topic)
  
• Blocks may disappear. (Forum Topic)
  
• A pasted block doesn't follow the mouse until places; it duplicates instead. (Forum Topic)
  
• A custom block added from the backpack doesn't appear in the palette. (Forum Topic)
  
• “Create new broadcast/message” dialog closes immediately on a touchscreen (Forum Topic)
  
• Code deletes itself when surrounding a forever loop with another forever loop. (Forum Topic)
  
• When dragging define blocks, their position changes relative to the mouse. (Forum Topic)
  
• The system keyboard pops up on number-only inputs on mobile. (Forum Topic)
  
• Block inputs may be blank and non-editable. (Forum Topic)
  
• Deleting a block by dragging it over to the palette sometimes makes the workspace shift left. (Noted by @EiskalterYeti)
  

Block Behaviour Bugs:

• You cannot drag a forever block on a mid-stack block. (Related GitHub issue)
  
• You cannot connect a hat block above a stack block. (Forum Topic)
  
• Forever blocks delete capped blocks when dragged on them. (Related Forum Topic)
  
• Dragging a block to the palette while there are blocks behind the palette will make it attempt to connect to the block. (Noted by @kwurteeqwerty)
  

Visual Bugs:

• The stop block's dropdown uses the incorrect colour in High Contrast Mode.
  
• When a comment is attached to a block, the line attaching it doesn't account for comment size. (Related GitHub issue comment)
  
• When spam clicking on a reporter block, the values can start building up weirdly. (Forum Topic)
  
• The font may be the system font on Windows. (Is this intentional or not?)
  
• Boolean blocks may have an outline. (Forum Topic)
  
• There are padding issues with dropdowns. (Forum Topic)
  
• Menu popups (variables, etc.) may have a black outline. (Forum Topic)
  
• Block input text is unnaturally large at full zoom-out. (Forum Topic)
  
• Dragging a block to the left edge of the palette lights up the stage.
  
• Zoom snaps back when workspace scrolled past left edge. (Forum Topic)
  
• Reporter blocks may be off-centered on some systems. (Forum Topic)
  
• Comments don't expand the workspace while dragging. (Noted by @hotcrystal)
  
• Sometimes when right clicking a variable block, there can be so many menu items that it goes over the menu bar. (Noted by @EiskalterYeti)
  

Fixed Bugs:

• A block that targets the sprite that it is in reports the default option instead. (Forum Topic)

I thought this was fixed? The issue is closed and I cannot replicate.

The glitch still occurs with a forever block, at least on Zen Browser/Firefox.

Do you mean like this?


I can't replicate the issue on Windows 11, Chrome or Firefox

No, I mean like this.

Oh, yeah I can replicate that

Here’s another one: comments connected to blocks don’t expand the space available to place blocks and stuff. This can easily be reproduced by taking a random block, adding a comment onto it, and then dragging the comment as far right as possible.

Added!

As of today, I cannot do anything at all. The green flag does nothing, I can't add anything to lists, I can't click blocks and make them run, be they hat blocks or otherwise; the editor doesn't work at all other than letting me change the posiitons of things.

Forgive me for being unaware, but why did Scratch even push this update? It doesn't take a particularly keen eye to realise that on half of every platform ever, almost nothing at all works. I downloaded an entirely new browser on my Mac earlier today thinking that it was a problem with some (also unfortunately broken) update to Firefox. Does “Spork” add anything? Did they even check to make sure it worked?

If you trigger the % bug, then try to drag out the

broadcast [ v] and wait

block, the block palette will disappear

for the blank inputs bug, users reported it with the color inputs years ago

when i try to add a message it goes “nope, you're not getting any new messages”
honestly i don't know why they changed the block editor

Broadcasts I placed after the update just don't work at all

i cant add spacing when i trying to make a broadcast

when you use the thing of thing block, when you change the second dropdown to a different sprite, it just deletes the block after a short delay. the only way of getting around this is by editing it in the sidebar then dragging it in

([ v] of [Sprite1 v])

this is the block im talking about

The block works fine for me.

Another bug: Creating a new sprite causes it to automatically switch to the “costumes” tab.
Actually, it may have always been like that. My bad.
