Most lightweight model for clean HDMI w/o overheating problem?

Like so many others, the pandemic has become an unexpected impetus for an upgrade from my current GX7.

I'm looking for a new body that's lightweight - hopefully a rangefinder style, not a DSLR style - but at the same time will not present an sensor overheating issue that I've read will arise with some models.

What do people recommend?

My of my glasses are from Panasonic, which means I'll be better off buying another Panasonic for IS. But it's not a deal-breaker, and an Olympus with the qualities I look for - clean HDMI without sensor overheating - will do too.

You say u want video but limiting yourself to a rangefinder body is the counter-productive. The GX series are the Panasonic RF styled bodies but they're also more photo-centric rather than video-centric so you're going to miss out on useful video features like some certain video profiles , better IS , better EVF's (except the GX8), better ergonomics,  side mounted SD cards and full size audio-in jacks.

The G80 has all those features over any GX camera (except the GX8 EVF) and its not much bigger than GX80 / GX7 II.
