I would like to report that this issue is back when using custom default8.png inside the "<resource_pack>/font" folder, with resolution higher than the default 128x128 pixels.

fontError_256x.jpg shows the error when adding a default8.png at 256x resolution. The line appears above some of the small letters. It also shows that there is a slight antialiasing going on.

fontError_1024x.jpg shows the error when adding a default8.png at 1024x resolution. This time the antialiasing is not present anymore. 

From what I can tell, that small artefact is part of the character above the small letter from default8.png

I'm also attaching the 2 higher resolution default8.png files so you can test them out: default8_256x.png and default8_1024x.png

I am also hearing isolated reports of this being an issue on vanilla worlds, with no RP attached.

Finally got around to making a world and testing this.(see attached)
1.19.81 - can reproduce
1.19.83 - can reproduce
1.20.12 - no longer an issue
So it's fixed somehow! 🙂
Cheers!

Also confirm 1.18.30 release. Also possible duplicate: MCPE-152220

Mojang has finally figured out what the problem was and will be releasing a fix on Tuesday, September 3rd.

Hey Matthew! This but has since been fixed. Did you encounter this problem?
