Big empty space for no reason

[owocean]

This happens every now and then after playing a fullscreen game. bspwm acts like there's a window there taking up space, but there is no window there. It doesn't have a title or anything. Restarting bspwm does not make it go away. I don't think it would matter, but the game that causes this is DUSKWORLD. It only happens sometimes, and goes away on restart. Anyone experiencing the same issue and know what the problem is? Or how to fix it? Thanks in advance

i have had this happen sometimes but i haven't been able to cause it on accident consistently before. typically it is a node without a client (i believe identical to a receptacle node created with bspc node -i).

to remove it, you should be able to kill it with the appropriate selector; if the currently focused node is the sibling to the receptacle node, and ideally a terminal emulator, you can run bspc node @brother -k. (though be aware floating and hidden nodes are still in the tree in places you might not expect and this will kill all child nodes too, so you may want to use the query below to inspect it first and/or try killing it by id instead)

you could also try inspecting it with something like bspc query -T --node @brother | jq which may help reveal if something very weird is going on. hope this helps!

}

i have no clue if this is useful or not. the other command you provided worked though :) thanks

Have same behavior, don't know when it appear, but then I can focus it, see preselection, move and, finally, close. It has same stats except for rectangles, of course. Recently updated bspwm from Arch repos to 0.9.10.

[owocean]

with the new steam update, this has been happening nonstop

[KorespondentAda]

Once appeared right after steam "Your friend launch game" popup, but not at first or every time. Steam itself worked in background. This "window", unlike receptacle created by bspc node -i for comparsion, has client with className and instanceName fields containing empty strings, but receptacle have client field null at all. It was not closed by bspc node <id> -c but -k works.

It appears to be steamwebhelper for me. Would a bspc rule to either dump it into an unused desktop or make it default floating fix this? I am testing it: bspc rule -a steam:steamwebhelper desktop=^8 state=floating

Also, this might be what is causing my fullscreen games to get kicked into tiled pretty regularly.

im wondering why i am not being hit with this.. i do have an external rule which hides steam windows that have no name and are exactly 64x24, due to this issue years ago, perhaps it is come back? i see there is a more recent report which looks similar

the exact rule i have is ugly but here it is anyway:

if [[ "$class" == "Steam" ]]; then
    # hide spurious windows generated by steam friendlist ui
    # https://github.com/ValveSoftware/steam-for-linux/issues/5584
        for w in $(xwininfo -root -children | sed -n 's/^ *\(0x[a-f0-9]*\) (has no name): ("Steam" "Steam")  64x24+0+0.*/\1/p'); do xdo hide $w; done
fi

i will investigate later as i wont be at the computer for a few days

[DeusHaeresis]

I'll have to try that external rule later, hopefully it works

First world problem, perhaps but it's just annoying having to cycle through nodes on the given workspace and bspc node -k'ing the empty receptacles/defunct nodes.

This issue has recently started cropping up for me. I'm able to minimally reproduce it from system startup by turning off my2560x1080 ultrawide screen in xrandr, then turning it on again. Usable screen space is limited to 1920 (1918, because borders = 1px, gaps = 0px)

bspwm -v: 0.9.10-50-g8fc2269

bspc query -T --node @brother | jq doesn't return any output

bspc query -T --node | jq:

    }
  }
}

The only way I can revert this is by fully quitting bspwm and logging in again. Restarting bspwm (bspc wm -r) doesn't have any effect.

bspwmrc:

#! /bin/sh

pgrep -x sxhkd > /dev/null || sxhkd &

# Polkit
