C-S-D stops appyling theme changes until I pkill -9 it

Hi,

I was experiencing this issue a month ago, then had to leave Cosmic for a bit due to AMD stuffs.

Now that I'm back, I'm definitely still experiencing this issue: after some time, for some reason, changing the theme from Light to Dark stops ... applying properly. Only some of the applets will change their theme, and applications like Firefox are not notified properly.

Every time this happens, I issue pkill -f -9 cosmic-settings-daemon and then changing themes again works.

~
❯ sysctl fs.inotify.max_user_watches
fs.inotify.max_user_watches = 99999999

~
❯ sysctl fs.inotify.max_user_instances
fs.inotify.max_user_instances = 256

I'm not sure this is fixed. I've taken recent nixos-cosmic updates and I can still repro this pretty trivially.

If you see #65, basically every single time I open the second Firefox instance and toggle-light, toggle-dark, C-S-D breaks. I do this after a reboot to get both of my Firefoxs open, and this triggers reliably 100% of the time.

Also quite bizarrely, some of the panel applets switch back to rendering in dark mode (aka, they're light icons on a dark background) but some don't, and Firefox doesn't toggle back properly. Maybe it "breaks" part way through the switch, I'm just not sure of the moving parts here. :(
