I was working on a track, left Renoise open and put my laptop in hibernation mode, after woking up the machine Renoise was somekind of frozen. I could click on somethings but nothing really happened and graphics got kinda glitchy. Happens everytime if going hibernation and back when Renoise open.
Hibernation is not really your friend with these kind of applications. You should put Renoise in the same class of applications that games are and you mostly cannot put your machine into hibernation when you are having a game running in the background.
Renoise is using the same style of drawing libraries that games use.(aside from if exclusive locked (audio) hardware likes to rewake from hibernation state)
I tested this one more time with alsa because when returning from hibernation also the whole interface was stuck and I couldn’t click on anything. But this time I waited some minutes, and after that atleast menubars became reachable.
