Focus doesn't return after running dmenu (X11/i3)

[Deewiant]

Noticed while testing #3709: Running dmenu from within Alacritty doesn't return focus correctly. That is, Alacritty does have keyboard focus after dmenu exits, but it thinks it doesn't (renders a hollow cursor).

System

alacritty --version: alacritty 0.4.2, but reproduces also on alacritty 0.5.0-dev (2c2104a) (current master)
dmenu -v: dmenu-4.9
Platform: Arch Linux, X11, i3

Logs

From alacritty --persistent-logging --print-events -e sh -c "echo foo | dmenu; sleep 2" on 0.4.2:

Here I waited about a second before pressing enter on dmenu, causing it to print "foo" to stdout and exit. At that point Alacritty should receive focus, but doesn't. Seems that glutin is not sending Focused(true) for some reason.

This doesn't seem to happen with other programs than dmenu, so I guess it's something special to do with the way dmenu draws on top of other windows. However it also happens only with Alacritty and not (at least) xterm or st.

[kchibisov]

nice, that's the other issue I've seen on X11 somewhere in alacritty, but I was never able to repro it and gather logs myself, since I'm not using X11, thx for reporting.

[kchibisov]

upstream issue rust-windowing/winit#1565

[mbaz]

I'm not sure I can reproduce (Arch Linux, x11, openbox, alacritty 0.4.2). When I press enter, I see foo and a full (not hollow) cursor on the next line.

[kchibisov]

It's pretty random to repro it IIRC, like it could happen sometimes.

[nemya9066]

can confirm this bug I would like to add that this cause copy/paste to no longer work within alacritty.
it's also not random for me It happen every time I run dmenu(on bspwm x11)

[mahkoh]

I believe this was caused by a bug in dmenu 4.9 and has been fixed for a long time now.

[chrisduerr]

I believe this was caused by a bug in dmenu 4.9 and has been fixed for a long time now.

Thanks for letting me know. Closing. If someone can still reproduce, let me know.
