Why an interlaced timeline: what is your source?

My source footage is UHD 50p, but I need to work in a 50i HD timeline because I need to output for broadcast in europe and I need to see the final output to detect morie and aliasing for example.

I am having this same issue.
Premiere Pro 24 & 25
across three Macs (Studio, M1Mini & 2017 iMac) in Monterey and Ventura
all using different Blackmagic Thunderbolt devices to playout to HD Monitors to check for interlacing issues or playback problems before broadcast (UK)

Exports aren't affected
and playback is smooth with High Quality Playback turned on but this presents other playback problems with the lower specced kit.

And sometimes under deadline pressure these playback issues prevent us from playing out direct to transmission room

There are work arounds but these are time consuming and weren't necessary in the previous iteration we were using.
PP2020 is still on our systems so I have confirmed that RHS jitter isn't an overlooked problem or part of the Blackmagic software

To clarify, this is only present on the lower field - and only on the right hand side of the screen. Upper field playback is as expected
And it is present even after rendering, if the High Quality Playback option is not selected

This seems to be the only thread I could find about this which feels surprising given the number of people who've used PP2024 for interlaced material surely...??
