Sign upLinux: Fractional length border edges lose some pixels #1288

It's possible this is related to #1279, or at least a fix for one will fix both. |

I opened this test in Linux and was unable to reproduce - I didn't see any of the errors above, they looked pixel-perfect when zooming as well. |

@gankro please remind me tomorrow. I recall you were able to reproduce it. Now we just need to capture it :) |

Yeah I'll double check it on hawkman. I expect this has gone away since y'all have rewritten the border shaders like twice since I filed this bug? |

If you run this test from gecko
layout/reftests/backgrounds/background-tiling-zoom-1-ref.htmlin Servo or in gecko withlayers.advanded.border-layers, some of the borders will have missing or extra pixels near the corners.This shows up in
tryon linux, as well as when run locally on the toronto office's "hawkman" machine (Ubuntu), although the two have different artifacts. I haven't been able to reproduce this on macos.Seems like some sort of rounding issue in the shaders, as the test case has divs with fractional widths.
