If I set AOVs to ouput velocity and motion vectors and disable image blur I get cuda memory allocation error on XPU render.
On Windows the VRAM just go up and uses all memory and becomes really slow, on Linux it just gives cuda error.
If I turn off those OAVs it just render normally and fast on both.
I am rendering ocean procedural and some geometry.

Anyone else having this issue?
Any tips to get around this?

I am on H21 build 559

It seems that it is something specific on my scene setup but I can not pinpoint what could be causing this, it have something to do with turn on point velocities on the ocean procedural LOP to output its information to AOVs it is some kind of memory leak.

Any tips would be welcome.
