From: Dale Zhao <[email protected]> [Why]: Renoir's pipe VM flags are not correctly updated if pipe strategy has changed during some scenarios. It will result in watermarks mistakenly calculation, thus underflow and garbage appear.
[How]: Correctly update pipe VM flags to pipes which have been populated.
