What causes it and has it been fixed in the next release?Yes.
It's still observable in a specific photo mode in build 10, can't say for the late builds. As for the cause, I'm afraid I'm the wrong guy to ask
what is the threshold before that starts to happen?I am having a problem with temperature of stars, (if they get too hot they turn black or disappear completely)
attach here the file se.log from SpaceEngine's installation folderSomething happened to my game where I just entered a star system, and the screen went completely black except for the pointer. And every time I try to open the game up again and go onto the planetarium, it stays that way, any suggestions on what to do?
