Looks like a GPU Runtime issue. we will file a bug and track it. Thanks.

Just sync with @xhaihao If this is regression, we need know which commit has not this issue for bisect. If it is bug, need more debugging for root cause.

wenqingx commented 1 year ago

@wangyan-intel sorry,this is not a regression, but a random R2R problem.

wangyan-intel commented 1 year ago

@wenqingx Could you please provide the clip for debugging?

wangyan-intel commented 1 year ago

This issue has been fixed by https://github.com/intel-innersource/drivers.gpu.media.vpl.public/pull/3147

wangyan-intel commented 1 year ago

@wenqingx Could you please close this issue? Thanks.

wenqingx commented 1 year ago

@wangyan-intel thanks your patch, close.
