Animation plays one frame in viewport

Hey friends!

Been working on an animation. Been viewing it in simplify mode in the viewport. Recently when i’ve stepped away from my computer and woke the monitor up, when i hit spacebar to play the animation in the viewport it only goes one frame ahead. If i quit blender and restart. All works just fine. Is this a bug? I just went from 2.93.3 to 2.93.4 and it’s still happening. Any ideas???

It’s likely the buffer gets emptied if you leave it long enough for the computer to go to sleep. That’s my best guess.

It’s only the monitor going to sleep not the computer. Thoughts?

Your monitor goes to sleep? :slight_smile:
