⚙️ List of bugs with the new block editor update (a.k.a. Spork) ⚙️
The website is that buggy that even the buggy app is better to useThey need to eventually.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:
- When adding an input to a block definition and undoing it later, the input variables will detach from the definition block. (Noted by @Reveerain)
- 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)
- 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)
- 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)
- Deleting a block by dragging it over to the palette sometimes makes the workspace shift left. (Noted by @EiskalterYeti)
- Control/Command + A no longer works in block inputs. (Noted by @altsrc)
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)
- Dragging a block to the palette while there are blocks behind the palette will make it attempt to connect to the block and possibly delete. (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)
Miscellaneous Bugs:
- After dragging in a pre-Spork define block from the backpack, you cannot drag the argument blocks from the definition.
Fixed Bugs:
- Block inputs may be blank and non-editable. (Forum Topic; does anyone know if this bug still occurs on new blocks?)
- Blocks may disappear. (Forum Topic)
- A block that targets the sprite that it is in reports the default option instead. (Forum Topic)
- Forever blocks delete capped blocks when dragged on them. (Related Forum Topic)
- Code deletes itself when surrounding a forever loop with another forever loop. (Forum Topic)
Can Scratch or Someone Fix This?

Reporter blocks and boolean blocks with comments attached to them are indented strangely. This does not apply to variables and lists.

Can replicate, though it is weird that it doesn't happen to variables & lists.

Happens when switching the language to Hungarian
The text should be in the same line as the prototype block, and it shouldn't go out of the block

After uploading a custom block from my backpack, some of it's variables became nameless, like this:

(letter (::variables) of [world])They still function fine. The variable itself is set to “this sprite only.” Renaming the variable did not have any effect.

everything is a question mark!Most likely unrelated to the Spork update (which occurred a bit ago); please visit one of the already-existing topics already made for this exact issue to report this instead.

I think someone mentioned this before but it isn't in the list
If you create a custom block with any name and than create a custom block with a blank name all the blocks stack on top of each other at the top of the palette.
