    Same problem here.

    As a work-around, modifying PostProcessPass.cs as follows fixed the issue for me.

    int amountOfPassesRemaining = (useStopNan ? 1 : 0) + (useSubPixeMorpAA ? 1 : 0) + (useDepthOfField ? 1 : 0) + (useLensFlare ? 1 : 0) + (useMotionBlur ? 1 : 0) + (usePaniniProjection ? 1 : 0);

    to

    int amountOfPassesRemaining = (useStopNan ? 1 : 0) + (useSubPixeMorpAA ? 1 : 0) + (useDepthOfField ? 1 : 0) + (useMotionBlur ? 1 : 0) + (usePaniniProjection ? 1 : 0);

    It semems that amoutOfPassesRemaining shoudn't be added for lensFlare beacuse lensFrae doesn't need buffer swapping.

    Note this also occurs in URP 12.1.5

    Yep, just ran into this. Weirdly doesn't happen to _every_ canvas but I'm not sure what's special about the ones it keeps...
