@onotole f.lux actually modifies this setting for activation at sunset. Then I assume it sets the "dark theme" back to unchecked, once sunrise happens. It's probably enabled by default in f.lux, so look in the settings there first.
I spoke too soon. Still crashing :(

Just wondering how to disable ''uncheck for currrent app''. Can someone help me? Can't figure it out.
Thanks in advance
