1569007 - Text input problems in Fenix and Focus+GV: cursor jumps around, characters are duplicated

Status: RESOLVED DUPLICATE of bug 1596920

(GeckoView :: IME, defect, P2)

Description

[Chris Peterson [:cpeterson]]

Steps to reproduce

1. find text field
2. start typing a sentence.

Actual behavior

cursor and letters jump around, spaces are removed, some text is duplicated

Info

Also reproducible in Focus with GeckoView 68, but not Focus with WebView.

I've noticed that typing incredibly slowly avoids the issue.

Closing as WFM because the original bug reporter says they no longer see this problem:

Focus has an old version of GeckoView. I asked the Fenix bug reporter to retest with the latest Fenix version.

Comment 4

[Chris Peterson [:cpeterson]]

The Fenix issue reporter has not replied about testing in a more recent Fenix version (using GV 69 Beta or 70 Beta), so I'm going to close this bug again.

I'm reopening this bug because two Fenix users are still reporting text input problems that affect Fenix (GV 70) and Focus (GV 69), but not Fennec (68). So maybe this is a problem specific to GV (and not Fennec) or this is a regression in Gecko 69?

One Fenix user reports that the problem seems related to the Gboard keyboard's suggestions causing delays and that typing in password fields works fine.

Hi Makoto, have you seen any text input problems like this? Could the Gboard keyboard's suggestions block the Gecko thread responsible for text input on the web page?

Looking this

Makoto, have you had a chance to look at this bug yet? The original bug reporter's steps to reproduce don't have many details.

[Chris Peterson [:cpeterson]]

Adding to GV's November sprint because this bug is on Fenix's list of top 10 GV bugs.

Comment 10

[Makoto Kato [:m_kato]]

Hmm, unclear to reproduce this. I am asking reporter to make sense this issue and reproduce this.

Comment 11

[Emily Toop (:fluffyemily)]

Removing from sprints until we have a way forward with this issue.

Comment 12

[Makoto Kato [:m_kato]]

This will be fixed by bug 1596920's fix.

Comment 13

[Makoto Kato [:m_kato]]

Asking reporter whether this issue is fixed. I think that this is already fixed by bug 1596920.

Comment 14

[Wil Clouser [:clouserw]]

It sounds like this is reliably reproducing on the FxA stage server right now if you don't have a test case yet: https://github.com/mozilla/fxa/issues/4788

Comment 15

[Makoto Kato [:m_kato]]

latest patch of bug 1596920 will fix this issue.

Comment 16

[Chris Peterson [:cpeterson]]

Moving some cursor and key event bugs to the new GeckoView::IME component.
