## Describe your issue / feature…

I was playing with submaps the other day, when I found Hyprland crashing randomly on activating/deactivating the submap. After a little inspecting, I suspect the issue stems from changing `hl.config(…)`when an animation is playing. I can consistently reproduce the issue aka. crash Hyprland with the following bind:

> **From hyprland.lua**
>
> ```lua
> hl.bind("CTRL + G", function()
> hl.config( { general = { gaps_out = 40 } } )
> hl.timer( function()
> hl.config( { general = { gaps_out = 20 } } )
> end, { timeout = 200, type = "oneshot" })
> end)
> 
> ```

Notably, the issue seemed not to be restricted to changing the same config value (i. e. `general.gaps_out`) in quick succession but occurred also when changing `hl.config(...)` whilst an animation from `swapsplit`/`togglesplit` was playing out.

I’m not sure if anybody can help me here. But I found that the issue seems only to happen when hyprland is launched through uwsm.
