Chinese input intermittently drops out, typing English letters instead on iPad (M5, iPadOS 26.3.1) and also on macOS

Title: Chinese input intermittently drops out, typing English letters instead on

iPad (M5, iPadOS 26.3.1) and also on macOS

Environment:

· Device: iPad Pro 13-inch (M5)
· OS: iPadOS 26.3.1 (23D8133)
· Obsidian version: 1.12.4 (299)
· Input methods tested: Apple stock keyboard, Sogou, iFlytek

Description:
When typing Chinese on iPad, the input frequently breaks: the composition window disappears and the Pinyin letters are directly inserted as English text instead of the intended Chinese characters. This happens randomly, often within a few sentences. After the dropout, I have to delete the stray letters and retype. The problem persists regardless of the input method used.

Steps I have taken to isolate the issue:

· Tested with different Bluetooth keyboards and the on-screen keyboard → issue persists.
· Tried on another iPad (different model) → same behavior.
· Used Apple Notes app on the same iPad → typing is normal, no dropouts.
· Disabled all third-party plugins and turned on Safe Mode → issue still occurs.
· Tried different Chinese input methods (Sogou, iFlytek) → same result.
· Disconnected charger and Bluetooth devices → no change.

Expected behavior:
Chinese input should work smoothly without interruption, as it does in other apps like Apple Notes.

Actual behavior:
Typing is frequently interrupted, causing the input method to fail and insert raw Pinyin letters. This makes writing longer Chinese text very difficult.

Additional context:
I have seen similar reports in the forum (e.g., [link to similar topic if any]) for both iPad and macOS. The issue persists in the latest version. This seems to be a cross-platform problem with Obsidian’s editor, possibly related to how it handles text input with Input Method Editors (IMEs) like Chinese input methods.

After further testing, I observed that the problem is more likely to occur when editing longer documents containing rich text elements such as bold markdown formatting, emojis (e.g., :green_circle:), and Dataview code blocks. The presence of these elements seems to increase the frequency of input interruptions.

Thank you for looking into this!

Same problem waiting to be attended.

iPadOS 26.4

Download and reinstall Obsidian. Let’s focus on the apple stock input method.

  1. Does is happen on both macos and ipados? or only ipados?
  2. Create a new vault, does it happen there?
  3. Does it happen in source mode?

I didn’t have chance of trying it on mac.

Source mode didn’t work.

A new vault works.

If this doesn’t happen in a new vault, it points to some third party plugin creating this problem.

In your own vault, enable restricted mode, default theme, and no snippets. Restart Obsidian.
Does the problem still happen?
