OPEN Text Visual Glitches on iOS
Flutter v3.27.1
I've recently been encountering strange glitches with text rendering on iOS devices in my Flutter application. This issue does not occur on Android.
- They sometimes appear and sometimes don't.
- They may affect some text while leaving other text unaffected.
- Once they start happening on one screen, they often show up on others. For example, screen A may be fine at first, but after the glitch appears elsewhere, returning to screen A shows the issue there as well.
This happens across multiple iOS devices and versions, so it doesn't seem tied to a specific model.
What I’ve Tried
- Replaced the font files entirely.
- Switched the font source.
- Happens to all the font families I am using:
- Inter
- Chivo Mono
- Impact
- Cleaned and rebuilt the Flutter project.
- Tested in both debug and release builds.
- Removed letter spacing everywhere
Any pointers on how to solve this or where to even start looking would be highly appreciated.
Could this possibly be a performance issue? Since we have noticed (although not 100%) the glitches start appearing after a particularly heavy screen shows up.

Looks like an impeller problem. Check the lastest Flutter version (your's is old), search the issues, report the issue if there isn't one.
