bug(android): when switching keyboards, backspace can sometimes stop working properly #11435

Open LornaSIL opened 2 weeks ago

LornaSIL commented 2 weeks ago

Describe the bug

Sometimes, when I type in one script and then switch keyboards to another script, the backspace key gets stuck and will not backspace. This only happens when I hold the backspace key down to delete a bunch of characters. If I just hit the backspace once, it doesn't get stuck.

However, I cannot reliably reproduce the issue, so I do not yet know what triggers this behavior.

Reproduce the bug

  1. Open Keyman Beta 17.0.322-beta
  2. Change keyboards to sil_euro_latin
  3. Type some text with perhaps a space
  4. Switch keyboards to an Arabic script keyboard like afghan_turkmen
  5. Type some arabic script text. Perhaps type an enter or switch layers, press and hold the backspace key.

Expected behavior

I expect a bunch of characters to get deleted. Often it just doesn't move. If I think type backspace once, I can then press and hold and it will backspace.

Additional context

I have two recordings which I will try to upload.

This first one I was not talking. The backspace worked fine as I typed Arabic script. At the very end it got stuck. It's too big to upload so here's the link.

This second one I tried to talk through what was happening.

I don't know how to reproduce this, if I figure it out, I will submit more information.

@jahorton this sounds like a context desync on keyboard switch.

@LornaSIL thank you for the report -- that's lots of helpful detail, hopefully will give us enough to track down the cause.
