From: Yikai Zhao <yikai <at> z1k.dev> To: Pip Cet <pipcet <at> protonmail.com> Cc: Gerd Möllmann <gerd.moellmann <at> gmail.com>, Helmut Eller <eller.helmut <at> gmail.com>, 74590 <at> debbugs.gnu.org Subject: Re: bug#74590: 31.0.50 [scratch/igc branch]; key input sometimes skip fcitx input method preedit box Date: Wed, 4 Dec 2024 12:55:04 +0800
Here attached the relevant output of "xscope".
t=116.64 is approximately the timestamp of a correct keypress (that
goes to fcitx);
t=116.83 is approximately the timestamp of an incorrect keypress (that
goes to emacs).
I just realized that you mentioned the x11trace tool. I will also try
to reproduce with x11trace later.
