Source/Program Monitor Mirror Glitching

*sigh* sorry I went on about windows, clearly didn't caffeinate enough today. you were asking about Premiere. I did put that in the report too, it is Premiere version: Premiere Pro v25.1.0(Build 73) 

hey thanks for the reply. Good to know! oh, I put that info up top in my initial report posting that I was on Operating System: Win11 Pro 64-bit on a PC but will also include that is version 24H2 (OS Build 26100.2894) if at all helpful. Appreciate any thoughts!

My Win11 (23H2) is working fine. We are using 25.1, I believe you are too, but you didn't say that in your recent post. There's a difference you know. I've been on Nvidia 566.36 (studio of course) and it's been stable.

the hdmi cable is directly into the gfx card, and I don't have a gsync enabled monitor. I've been on this same build of pc, as I built it for primarily editing but as bonus works good for gaming too. Which up to now, both were without tearing issues or the like. So far any has only been happening to me in Premiere, and I guess only in v25. Not sure if Win 11 has any part in it too. 

Hi @katieto - What type of cable are you using to connect to your monitor?  Is it plugged directly into the graphics card?  In the Nvidia Control Panel do you have g-sync enabled?

Thanks again for checking in Jamie! So it's happening and I'll try to explain what was going on while it did. I was playing back from my selects sequence timeline which shows up in Program normally. The source panel just looks like I've loaded that same shot in, but I didn't and instead should contain the multicam sequence loaded there. See my screenies.

Program mirrored over the Source Panel this time. It had what I can best call a 'screen tearing' on the very left end of the mirrored Program video playing over Source as if it wasn't fully there copying it, which you've maybe seen already in my attached vid from initial report since I captured it live playing back.

When it happened, I went to use the snipping tool to take screenie, and it's as though Premiere refreshed during me clicking and back, which is why it looks "fine" like a clip loaded to source. I even tried my shortcut screenie command but that seemed to refresh it too. Went ahead and moved the scrubber again, still there, only this time I took a phone pic to more clearly highlight and retain this 'screen tear' I mentioned. Sometimes it's a small one like this, sometimes 1/3 of that panel is see-through past the glitch thing.

I feel like it's related to something with how things are refreshing? Somewhere? don't know how or why exactly or if I'm just cursed lol? Hope that makes sense. 

What a mystery indeed!!

here is how it should look:

Here is when it did the mirroring from the Program panel over my Source, no tearing but still wrong, the left source side should have the multicam from my other screenie:

Hi @katieto - Can you take a screenshot of the entire window next time it happens again.  There a bunch of tweaks you can do in the Nvidia app in the settings section there are features labeled Nvidia overlay and game filters and photo mode.  In the System setting you can change video enhancement modes. and in the graphics settings there are global settings.  If you didn't manually change any of these then we can rule that out.

Nope, no reproducible steps came to light because of it being quite random and also present in many projects, so not tied to one particular thing far as I can tell. I think I already gave you all the project file I consistently saw it in when I wrote this report.

As for Nvidia app, is there something more specifically you're asking if enabled or not? I don't have any overlays if that's what you mean. At any rate, I'll go ahead and update that driver back to recent.

Hi @katieto - I would say install the current latest Studio driver 566.36, since we know thats not the problem.  Do you have any features in the Nvidia app that are enabled?  Have you identified any reproducible steps or is it still random?

Thanks Jamie! I realize that. I'll turn show audio units on when doing microadjustments on the sync as needed if I discover an area that's off by just a bit and needs that micro nudging, which is what I was doing when this all kicked off. I generally don't edit in that on a whole but thanks for pointing it out.

Importantly, I wanted to also report that despite grabbing that driver, the mirroring issue is still haunting me so unfortunately I don't think that was the culprit so, it's still there.
