I just wanted to say that I’ve been having this EXACT issue probably since March, and still have it. It’s annoying AF and I have no idea what’s causing it, or how to fix it. Whenever it starts happening, I have to save everything and close/open UE again.
The most annoying part is opening all tabs again, and remembering what I was doing.
there are multiple reports of this bug for almost a year now, and no actual fixes that work apparently.
the workarounds include installing a (VERY) old geforce studio driver or switching to vulkan. none of which are a proper fix.
Any fixes yet? I’m on UE 4.27.1, 32gb ram, rtx 3080, r9 5900x
