I’ve been having this problem frequently lately. Is there any diagnosis about what causes it or what can I do to reduce it?
I fixed that problem when I changed the OS from “kde plasma” to “linux mint xfce”. I couldn’t render more than 10 frames in a row and the workflow had become very tedious.
I think it was due to instability when I updated the system, probably my hardware is obsolete.
*When I update the system I change my main email and that is why I reply with another account.
