Content rendered in incorrect position

When opening the PDF above, in the middle of page 1, there should be 7 items (1) to (7).
It works well on PC, as well as Adobe Reader on Android / MuPDF.

However, when I tried to open with Radaee PDF Viewer, the end of point (1) is incomplete, and (2) to (7) are rendered out of bound.
Are there any possible fix for that?

Moreover, The thin edge(s) of the black boxes may disappear when zoomed out using 1280x800 screen, but acceptable on 1920x1080 devices. Will future release support anti-aliasing so that thin lines can be displayed properly?

fixed, a special type3 char has text status operation.
maybe update tomorrow.

The new Version 3.0beta9 has a fix for your issue.
