empty space on desktop after waking from sleep mode

[hrvstr]

Hi, I have an issue when I wake my computer from sleep mode where yabai won't fill all available space on my desktop. I then have to create another space and kill the first to get it to use all available space again. How can I fix this?

Setup:

• mac OS 10.13.6 (17G7024)
• ultrawide monitor (3440x1440px)
• yabai (stable - not github) running as a brew service
• scripting-additions not installed - SIP enabled

Steps to reproduce

• Go to sleep mode with a couple of windows tiled
• Wake computer up -> not all available space is filled
• Create new space and kill the old one
• All available space is used again

Config file:

#!/usr/bin/env sh

# global settings

yabai -m config mouse_follows_focus          off
yabai -m config focus_follows_mouse          off
yabai -m config window_placement             second_child
yabai -m config split_ratio                  0.50
yabai -m config auto_balance                 off
yabai -m config mouse_modifier               fn
yabai -m config mouse_action1                move
yabai -m config mouse_action2                resize

# general space settings
yabai -m config layout                       bsp
yabai -m config top_padding                  0
yabai -m config bottom_padding               0
yabai -m config left_padding                 0
yabai -m config right_padding                0
yabai -m config window_gap                   20

I've been having a very similar issue lately which I can't reliably reproduce, where yabai loses some of its managed windows so new windows tile over them. Here's a screencast: https://streamable.com/h6fau

Your idea of resetting the space by destroying the current one works quite smoothly, so I wrote a small script that creates a new space, moves it so it's right next to the current one and then destroys the current one, thus moving all windows over to the newly created space and keeping the order of spaces as if nothing ever happened.

# reset current (non-fullscreen) space
yabai -m query --spaces --space | jq -er '."native-fullscreen" == 0' > /dev/null && \
    yabai -m space --create && \
    seq "$(yabai -m query --spaces --display | jq -r 'map(select(."native-fullscreen" == 0).index)[-1]')" \
        "$(yabai -m query --spaces --space | jq -r '.index + 1')" \
        | sed '$d' \
        | xargs -I{} yabai -m space {} --move prev && \
    yabai -m space --destroy

I have this set to a keyboard shortcut in skhd so I can easily reset the current space.

It's not a fix, but it's at least a working bandaid.

I wanted to add that it's not only happening when waking up from sleep. It can reproduce it now by opening a new tab in Terminal.app.

[dominiklohmann]

See #68 for that.

Can you reproduce the wake from sleep issue on master? I can't reproduce this..

[alextes]

Hmm, I do get empty spaces, not after sleep, and not from tabs. It sounds like it may be an unrelated issue but I'll subscribe here and wait for this to pan out first.

Thanks dominik for the workaround.

If I find a way to reliably reproduce I'll share.

Can you reproduce the wake from sleep issue on master? I can't reproduce this..

I uninstalled the stable version yesterday and installed again with brew install --HEAD yabai.

After sleeping the computer over night I woke it up this morning and the bug appeared again. I could not reproduce it when going to sleep mode for a short time so it might not be related to sleep mode after all. I will try to keep track of what windows are open when I experience it.

[dominiklohmann]

In the Energy Saver system preferences, do you have "Enable Power Nap while plugged into a power adapter" enabled? That setting causes the NSWorkspaceDidWakeNotification to fire every so often while the computer is asleep.

[hrvstr]

Nope, Power Nap is disabled. I observed the bug the last couple of days and I am 90% sure it's related to the Mail.app. I experience the bug mostly when I open the Mail.app window when it was previously minimized. Still can't really reproduce it reliably because it doesn't happen always...

[alextes]

I found a way to reproduce my issue, but it seems unrelated, let me know if you'd like me to create a separate issue.

I have an app Kitty. Which I open using:

cmd - return : /Applications/Kitty.app/Contents/MacOS/kitty --single-instance -d ~

If I hide Kitty and trigger a new window to be created, the app unhides, and creates a new window. This results in two windows but three spaces, one of them being empty.
yabai -m query --windows --space

Restarting yabai makes the empty space disappear. Same as recreating the desktop.

[koekeishiya]

@alextes I can see how that could be a problem. Would you mind creating a separate issue for that? Thanks.

Edit: I created a separate issue and copy-pasted your post, see #233

[hrvstr]

Just wanted to give a small update on this issue:

I now switched from using the default Mail.app to Spark and the problem mostly went away. I still have the problem sometimes so it seems like other apps are triggering this bug as well but it's not every day like it used to be.

[koekeishiya]

I think this issue has got somewhat derailed, and I have yet to have this problem occur for me.
There has also been some changes to try and deal with 4k/5k displays in the latest version, and that may catch this issue as well. Closing this.

Feel free to create a new issue if you still experience this on the latest version. It would be nice if you could include the result of yabai -m query --windows --space and a debug log dump if that happens (run as yabai --verbose or add yabai -m config debug_output on in your config-file. If you run through brew you need to specify path to logfiles for stdout and stderr in the service .plist file).
