kstars GUI button colours changing if left running overnight (macOS)
I left kstars running overnight for an imaging session and I woke up to find the screen was unreadable (EKOS had also crashed but that's another story).
Last night I didn't have an imaging session running but I did have the GUI tuning idle and when I awoke it was the same problem. The button background had gone to white and there was nothing I could do to get it back to normal other than exiting kstars and restarting.
I have Dark Mode permanently switched on on my Mac.
