Bug report: iOS epub reader

justin___ · 2026-05-06T00:06:23+00:00

On iOS epub reader the page back function causes a pixel shift of the page content to the right. If you press back multiple times or flip forward and back it makes it unreadable.

Thanks for the report. Can you please also let us know, which Zotero version, which iOS version, and which device you see this on? Also, does this happen in every epub you open, or specific ones? In the latter case, can you please share such an epub by mail to support@zotero.org and mention this thread.

For reference, a similar issue happened on android with the first iteration of the epub implementation:https://forums.zotero.org/discussion/130773/android-epub-display-text-cut-off-on-left-side

This happens on any epub, not a specific one.
