I found that when using the warp stabilizer the output is different then what's visible on the timeline. The stabilized footage is off the frame and you can see the footage underneath. that's not how it looks in Premier. This must be a bug of some kind. Please advise.

Same issue. UHD footage in a 1080p timeline. If you use "Scale to Frame size" vs "set to frame size" it will render correctly at 1/2 resolution but this limits your re-framing options and sort of defeats the purpose of shooting 4K for 1080p. If you set to "full" the bug does not appear.
These are the sort of show stopping bugs that give Adobe a bad name for having glitchy software.

I'm also having this truly annoying issue with some 4k footage in a 1080 timeline. It's fine once it's paused or rendered, but just watching it down gives this error in the frame.

This happens when I work with 4K footage on a smaller timeline (1080, 2K, etc). Very annoying.

Same issue (although my stabilized footage appears to want to slide to left and up). Seems to persist even with the nesting "trick". Doing a "Sequence > Render In to Out" will render the effect correctly, but real-time preview is no good.

Same here with UHD on a Windows System. Happens in CC 2019 and 2020.

Yes, that could be correct. To be honest, I have been behind the wheel on the Mac operations that I've been comparing to, so I might have missed some of those details. It was more a "hey, has anyone else noticed this? No? Nuts." type scenario :-P
Good suggestion on the workaround. I shall give that a go!
I'm on Mac with UHD media in a 1080 timeline, and experience the same exact issue.
Darren maybe you think it's not as badly because that particular clip didn't need as much stabilization? I think the shrinkage is inversely proportional to the amount of relative upscaling Warp ended up doing.
It jumps to a small size upon playback, jumps back to correct scaling upon pause.
One workaround is to modify the scaling (e.g. to 50.1%). Personally I don't like Warp to scale for me, so I use it in Stabilize+crop mode and then scale the clip myself in the transform controls.. which also happens to work around this bug.
Also, try setting playback quality to Full and see if it helps.

Same thing happening here. For us it really only appears to be on Windows systems, as the Macs don't seem to show it (or at least not as badly).
Essentially here, as soon as you hit play on a stabilised clip that is a different resolution to the sequence, it shrinks down. Stop playback and it goes back to normal.
Basically WS is currently unusable on the Windows systems without the old nesting trick.

I'm having the same issue. It only happens with true 4k footage for me and not UHD footage.
