Status: RESOLVED INVALID

(Core :: General, defect)

Attachment: List of failing tests

The failures roughly fall into these groups

 (1) 621253-1-externalFilter is timing out doing
REFTEST INFO | Updating canvas for invalidation
REFTEST INFO | DoDrawWindow 0,0,800,1000
REFTEST INFO | [CONTENT] MakeProgress: STATE_WAITING_TO_FINISH
REFTEST INFO | [CONTENT] MakeProgress: waiting for MozAfterPaint
REFTEST INFO | [CONTENT] AfterPaintListener in http://localhost:4444/1307161617192/2/bugs/621253-1-externalFilter.html

This looks like a pretty bad legitimate bug.  Maybe in the harness.

 (2) test or reference is blurry, as if it's being resampled.  Seems to be occurring with zoom tests.

 (3) test has a thin gray line around window bounds.  Looks like a slight mispositioning, or bad snap.

 (4) antialiasing microscopically different for test/ref.  Might be another instance of slight mispositioning, but some of the tests look like grayscale vs. subpixel AA.

Looks like Rob fixed several of these in bug 637852.  Thanks!

Closing GTK2 related bugs since we removed GTK2 support at the beginning of 2018 in bug 1278282. Probably best to open a new bug in the unlikely event that any of these are still relevant.
