Summary

After stacking windows, I can cycle through them fine with my key bindings (alt + [, alt + ]) but if I try to click on one of the stack bar tabs, komorebi freezes and I have to restart the process. Even when hovering over the bars I get an hour glass mouse icon.

Looking for configuration files in C:\Users\Paul

Found komorebi.json; this file can be passed to the start command with the --config flag

Found C:\Users\Paul\.config\whkdrc; key bindings will be loaded from here when whkd is started, and you can start it automatically using the --whkd flag

This has come up a few times and I have been suspicious of the network widget. Try to disable the default interface or if that does not work, the entire network widget.

So after completely disabling the Network widget, I have seen some improvement, but I do still see the "loading" mouse icon when hovering over stacked tabs at times - but the crashes have mostly gone away.

The stackbar feature isn't receiving updates (from me) anymore - if it's not already marked EOL in the schema I'll make sure it's marked for the next release

The "official" recommendation is to use a status bar since all the major ones (komorebi, yasb, zebar) support stacked containers

If someone wants to submit a patch to improve any current issues they are welcome

I have been planning to change the network widget somehow, but I have no free time whatsoever lately.
So that will come at some point. 🤞

I haven't been able to test from main - will the loading mouse icon fix be included in a future release?

You can try to install the nightly release for now.

Things will start picking up after the summer, including a new release.

Thanks, the nightly release seems to have fixed the loading mouse icon issue. Also I've noticed fewer crashes overall now that I have disabled the network widget.

Since this is fixed on the master branch I'm going to close this issue - keep an eye out for the next release later in the summer!
