This is a known deficiency of runtime effects, next step is to fix how they manage function signatures to solve the problem. Bug: skia:10939 Change-Id: Id934e0acdf774b03bd6edce78d7b2c077bdeae00 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/360603 Reviewed-by: John Stiles <johnstiles@google.com> Commit-Queue: Brian Osman <brianosman@google.com>
