First letter flies to front of line in pinyin

[jidanni]

If I try to type 正常 here in a Github issue, I end up with n至常. 欲打如本行，必先於 bash shell command line 打，再複製到 GitHub. Else when I try to type 欲 the first letter flies out in front. ~~By the way, to type fuzhi, well, even in the bash shell, I need fuzhzhzhiii4 before finally seeing the precious two letters, "複製"!~~

It seems it's not reproducible from my laptop. Perhaps it's fixed in newer ibus (1.5.30)?

ibus 1.5.30-rc1 has has this line in the release note:

• Fix preedit issue with X applications https://github.com/ibus/ibus/commit/719792d300579c1bfdf43251a83c6ed4e5594c07

OK I'll wait until that reaches Debian sid.

ibus 1.5.30 is in Debian sid. Does it improve anything?

Note: this is when intending to type "zheng..." into a GitHub comment in chrome beta on desktop.

注意 the problem only happens in Chrome when typing into a GitHub comment, not in emacs or shell.

Please share the whole config by running this in shell:

gsettings list-recursively org.freedesktop.IBus.Chewing

Also your beta chrome version. What desktop environment are you using?

Today still on my slower computer: "n證chag". But on my faster computer I didn't see the problem. So maybe it's a CPU speed issue.

Typing as fast as I can in Chrome that is running in GNOME Xorg on QEMU, and intentionally throttled the CPU. It is still not very slow but there is visible lag.

I still can't reproduce this issue so it might be tricky to fix it.
