Dark mode keeps resetting to normal mode
I'm using dark mode, but it keeps resetting to the normal mode.
This happens after reboot, wake up, and sometimes after starting an app that I use in fullscreen mode.
It seems like some applications reset this setting, and that it does not persist after reboot/sleep.
Please help! This annoys the cr*p out of me.
