This oscillating is causing numerous performance alerts to be fired.

The first instance of the oscillation happens at #193808 but it may not be the cause of the issue. Since it is flakey it may be before that.

  • test: flutter_gallery_macos__compile
  • sub_result: release_size_bytes
  • host_type: mac

    This appears to be the result of #193317 and the different values are the result of compiling with different sdks.

    @vashworth how would you like to handle this? This is spamming the performance dashboard =(
