Hi,=A0=0A=
Emacs sometimes takes 100% CPU after I switch emacs graphic frame to inacti=
ve.=0A=
This patch will fix the issue.=0A=
=0A=
Reproduce steps:=0A=
1. Build Emacs with gtk3 and xinput2 on Ubuntu 22.04.=0A=
2. (setq x-use-fast-mouse-position 'really-fast) in early-init.el.=0A=
3. On a windows-host start a X11 server, and ssh -XY ubuntu-host:emacs to S=
tart emacs with X11 forwared-frame, and open emacs "src/eval.c", enable the=
show-paren-mode in emacs.=0A=
4. On the windows host, move the mouse out of emacs-graphic frame first, th=
e move the mouse in emacs-graphic frame and click.=0A=
5. On the windows host, switch the emacs-graphic frame to inactive (switch =
a native windows app to active).=0A=
Repeat steps 4,5 sometimes the emacs will takes 100% CPU.=0A=
=0A=
The issue won't happen if set the x-use-fast-mouse-position to `t`=A0or=A0`=
nil` instead of the 'really-fast.=0A=
=0A=
According to my debugging and tracking the variables, I found that=0A=
1. the xterm.c:21710 will let "dpyinfo->last_mouse_motion_frame =3D NULL;",=
then =0A=
2. later calls `x_fast_mouse_position` will no chance to let "XX->mouse_mov=
ed =3D false", then =0A=
3. the function some_mouse_moved() in keyboard.c always return true; then=
=0A=
4. the function timer_start_idle() in keyboard.c will be called again and a=
gain, which leads 100% CPU usage.=0A=
=0A=
As contrast when setting the x-use-fast-mouse-position to `t`, the "XX->mou=
se_moved =3D false;" always run, then the issue won't happen.=0A=
=0A=
Please help review the patch. Thanks=0A=
