Able to reproduce this issue on reported version 64.0.3249.0, latest canary 64.0.3260.0 using Windows 10, Mac 10.12.6 and Ubuntu 14.04 and the issue is seen from M-50 (50.0.2641.0). Hence considering this issue as Non-Regression and marking it as Untriaged

We apply this transform in the compositor, right? Looks like we need better filtering.

+chrishtr@ for thoughts.

If we want better quality we should maybe scale at raster either by not scaling the layer and scaling the paint or not promoting to composited layer.

Agreed, seems to be a filter issue, not scale.

Its not clear if we need some web apis to support this, or we should not be promoting in some cases. But it doesn't look like a regression.

chrishtr@ reply seems to suggest this isn't high priority to address? So downgrading priority and marking Available.
