This bug causes Scratch to not react to key presses, which can impact on projects that need key presses to work, and can mean Scratchers can't program, due to some blocks needing to have words typed in them to work correctly. This bug is only seen with {{wp|Firefox}}. There are currently no ways to fix it forever, but it has been found that clicking outside Scratch (such as address bar) fixes it temporarily.{{citation needed|date=April 2018}}

This article is about bugs in Scratch itself. For bugs in computer software, see Bug.

There are many notable bugs in Scratch. Some may just be graphical, some might impact coding, some might make text missing and some might show extra things.

Current Bugs

Wrong Font Bug

In the Scratch 3.0 Paint Editor, sometimes the Sans Serif font displays as a larger Serif font. There is no known cause and solution for this bug, but the workaround is to use the Chinese, Japanese, or Korean fonts instead, as they all look very similar to the Sans Serif font.[citation needed]

No Last Post Bug

Main article: No Last Post

In May 2017, when spammers were active, on some occasions the "last post" field next to a subforum description would be missing. Though it died down after a while, later changes to the forums seemed to bring it back. The reason why this happens remains unknown.[1]

Disappearing Comment Bug

Main article: Disappearing Comment Bug

Mainly found in Scratch 3.0, this bug causes profile, project, or studio comments to not show when attemping to view it. Sometimes, when the message for the comment is clicked, the comment section won't load. Then, if you try to view the page where the comment is without the direct comment link, the comment will not be shown. This can cause the inability to view, reply, delete, or report the comment. To fix this, do a hard refresh.

Fixed Bugs

See also: Flash Player/Bugs


Disabled Keyboard Bug

This bug, seen only in Scratch 2.0, caused Scratch to not react to key presses, which could impact on projects that need key presses to work and could mean Scratchers can't program, due to most blocks needing to have words typed in them to work correctly. This bug was only seen with Firefox. There were currently no ways to fix it forever, but it had been found that clicking outside Scratch (such as address bar) fixed it temporarily.[citation needed]

Semicolon Glitch

Main article: Semicolon Glitch

The Semicolon Glitch was a bug that caused a semicolon to be displayed at the bottom left of each page. It has since been fixed, but it has been brought back a few times on April Fools' Day.[2]

Disappearing Text Bug

Main article: Disappearing Text Bug
The bug, shown in a project.

The Disappearing Text Bug was that text in some projects would disappear. It was seen in blocks with written text inside or dropdown menus. In some cases, only some text would disappear, but sometimes, almost all the text in the project would disappear.[3] It has been fixed, and although it was reported to have appeared again in Scratch 2.0, it hasn't been seen for a few years.[4]

Variables Not Fully Hiding

In Scratch 2.0, sometimes, variables do not completely disappear from the Stage when hidden via the checkbox next to its name. The exact cause is uncertain, but it is speculated that quickly switching costumes or backdrops can cause it.[citation needed]

White Text

In Scratch 2.0, in Firefox, the project website loaded with black text appearing white. The cause was unknown, but it might have had to do with the Disabled Keyboard Bug.[citation needed]

Speech Bubbles With Empty Space at the Bottom

Sometimes, there is extra space at the bottom of a speech bubble.

ln Scratch 2.0, when changing to fullscreen, the outside of a speech bubble got amplified the correct amount, but the text appeared a bit smaller relative to the bubble. The result is that the speech bubble was a bit taller than it was supposed to be. This only happened with speech bubbles with lots of text, or large speech bubbles.
