Kitty dropping characters on fast input

[dezfx]

Typing fast or using external char input (in my case a yubikey) drops characters.

Linux, local build @ d72098b
This issue was introduced relatively recently, I think.

[dezfx]

Test: ran with --debug-keyboard, typed 'git', expected 'git', got 'gt'

Debug output:

According to that debug output all the key events are being correctly processed, and I cannot replicate your issue. What IBUS engine are you using? And does the problem go away if you run kitty with

GLFW_IM_MODULE=none kitty

[kovidgoyal]

I just pushed a commit that shoud provide even more debug output with --debug-keyboard post the output from that.

[dezfx]

GLFW_IM_MODULE=none kitty addresses the issue. Let me grab that debug output.

[dezfx]

Having trouble getting a repro without a full yubikey hit. I have ligblfw3-wayland installed with libibus-1.0-5. Not sure specifically what downstream might be interesting.

[kovidgoyal]

Post the debug log with yubikey, it might still be interesting.

No followup, closing.
