Two such (or extremely similar) issues reported in last week - what is your ibus version?

[adamscott]

@Zireael07 According to ibus version, it is IBus 1.5.29-rc2.

[HolonProduction]

As stated in #82338 downgrade IBus until they fix the issue. The dead key not being previewed is a regression from the multi threading of the scene tree (this is where the error in the console comes from). See #85306

That said maybe we should change the behavior of the display server to not straight out ignore all input events until the event, that IME finished comes in (IBus doesn't send it right now). This is why Godot becomes completely unusable but other apps only have problems inserting the dead key.

@HolonProduction I reported the issue to IBus, just to make sure.

[HolonProduction]

I think this is already part of ibus/ibus#2585 (I added the information there too). But maybe the issue gets more exposure this way :shrug:. Also I didn't catch the journalctl message. Maybe add it to the other issue as well.

The ibus bug is fixed already, but it will only be solved truly when 1.5.30 is released with the fix (don't know when that'll happen). For now at least I'll be using the Git version.

It seems there is a workaround but I haven't tried it:

The workaround is to switch the input focus two times after you type dead_acute + o.

I have the same problem on Ubuntu. Both in the editor and in the IDE, Godot no longer responds to keyboard input when I type dead keys. One issue is that the problem is only present in godot 4. I tested it just now in godot 3.5 and this version does not have this problem. I did a new fresh installation from scratch using Ubuntu 24.04 to see if the problem was my installation, but the problem persists. I tested on Xorg and Wayland.

My configuration: OS: Ubuntu 24.04 LTS x86_64 Host: Nitro AN515-57 V1.20 Kernel: 6.8.0-31-generic DE: GNOME 46.0 CPU: 11th Gen Intel i7-11800H (16) @ 4.600GHz GPU: NVIDIA GeForce RTX 3050 Mobile GPU: Intel TigerLake-H GT1 [UHD Graphics] Memory: 4958MiB / 15767MiB

Yeah, I still have the same

1.5.30 was released, but what might become an issue, is that the latest ubuntu lts seems to ship with an effected version:

Not sure what ubuntu's update policies are on lts releases, but I wouldn't count on them updating it.

I would recommend that an affected Ubuntu 24.04 user reports this bug to Canonical, they need to update their ibus version.
