【回答済み】2026/05/04 10:03 [不具合報告] iPad miniでステージ上の変数表示が低品質

2026/05/04 10:03:33 に jwm***@***.com からの smalruby.app への不具合報告をいただきました。

Variable on stage looks low quality (pixelated value, jagged corners, etc)

No programs reproduce this.
Reproduction steps:
1. Simulate a iPad mini
2. Go to smalruby
3. Keep the stage size default
4. Create a new variable or show my variable
5. Put the project on fullscreen
6. See the variable display
I think this happens with lists too? Not that big of an issue

開発チームからの回答をお待ち下さい。

Thank you for the detailed bug report and reproduction steps! We will investigate this issue, starting with reproducing it.

We have created an issue to track it: smalruby/smalruby3-editor#726

Thank you for your patience while we investigated this.

We were unable to reproduce the low-quality variable display on real hardware:

• On a physical iPad (iOS Safari), the variable monitor looks sharp in fullscreen — no pixelation or jagged corners.
• On scratch.mit.edu (upstream Scratch), the monitor renders identically, so this is not specific to Smalruby.

We noticed your reproduction steps begin with "Simulate an iPad mini." Device simulators / browser device-emulation can rasterize at non-integer scale factors and produce blurriness that does not occur on real hardware, where Safari rasterizes the scaled layers at the device's native resolution. We suspect that is what happened here.

Because we can't reproduce it on a real device and the behavior matches upstream Scratch, we're closing this for now.

If you do see this on an actual device, could you let us know:

• the exact device and iOS/Safari version,
• whether it was a real device or a simulator,
• and ideally a screenshot?

We'd be happy to reopen and dig in further with that information. Thanks again for the report!
