Random time dilation in editor without time dilation logic

Hi there,

I’ve got a strange bug with the editors that seems to speed up and slow down the playback of the entire editor.

The bug seems to appear after the engine being open for a while (a couple of hours) and I have been using a lot of Sequencer and Persona (animation blueprints and montages). Apart from that I can’t really give any specific repro steps.

There are no time dilation nodes in the blueprints of the project, so it isn’t this. It also appears to be random as to whether it speeds up time or slows down time. It effects all engine elements at once, and despite the settings having a fixed frame rate of 60fps, this also seems to vary along with the time dilation effect.

The only thing I can think of is that it has been rather hot in the UK over the past few days where it’s started happening, my PC seems to be running at normal temperature ranges, and the rest of my PC and programmes are not affected, but could some sort of overheating cause the tick rate to change in engine?

Any help would be appreciated.
