Thank you for your message @ronald_a, unfortunately I don't use cop in my case, just instanced lights but also see that we have one blinking non-instanced.

Hello @brians,
We're still on same kind of project (another) with short deadline and got same light blinking and rendertime exploding..
Support won't project because too heavy... so it would take a time to create same bug in a lighter project... Isn't your job ?

Note that once GPU vram is full, GPU card become useless and rendertime jump by a factor of 4 here.
A 4090 comp become equivalent to a 2080ti comp here..

And it also make 2080ti even more useless.

In brief you have a big problem on the memory management for karma XPU.
It force us to optimize scene and hide as much thing we can to pass bottom the bar of GPU vram.
Feel like working for realtime here

Are you aware of that ? If that somethings in your radar for improvements or an unsolvable technical limitation.

Is it possible you could submit a bug with a repro scene that exhibits the flickering issue?

Project link is shared on same bug than the one of "5K" (same scene) with multiples e-mails with multiple video record illustrate the problem on multiple pass.

For now I havn't succes to reproduce it in a simple scene.
I have also have a deadline and we do our best to deliver project in time.
