Description Jonathan Haas 2023-03-16 12:51:43 UTC

This is a local tracking bug for this upstream issue:

https://github.com/ibus/ibus/issues/2480

In short, the commit https://github.com/ibus/ibus/commit/506ac9993d5166196b7c4e9bfa9fb0f9d3792ffa introduced a regression in thread safety, which sometimes causes key events to be reordered, for example the key up event for a specific key can happen before the key down event, which can confuse applications and cause "stuck keys". A related issue is that pressing lots of keys very quickly can cause crashes.

I'm not completely sure, but it looks like this bug only happens with X11 based applications, including wine games.

Comment 1 Fedora Blocker Bugs Application 2023-03-16 12:56:58 UTC

Proposed as a Blocker and Freeze Exception for 38-final by Fedora user jonha using the blocker tracking app because:

 While there's no obvious criteria violation, this regression is causing a lot of issues for people who play games on Fedora, see for example  https://www.reddit.com/r/Fedora/comments/11s10fu/comment/jccl7os

Maybe this could be put under the "Default application functionality" criteria with ibus as default application.
