Circular progress indicators animate slowly #3599

Closed

Description

@HansMuller

The material gallery [progress indicators demo] only manages about 30 fps, even with the non-standard elliptical progress indicator commented out.

The problem appears to be SKIA arc drawing - https://bugs.chromium.org/p/skia/issues/detail?id=5227

    I'v worked on getting the Skia fix in, but the performance improvements are marginal at best and the stuttering is still present.

    @chinmaygarde my understanding from our conversation just now was that progress indicators were not the target of https://bugs.chromium.org/p/skia/issues/detail?id=5227?

    @eseidelGoogle I've updated flutter-team-archive/engine#2995 and it seems like the fix solves our issue.
