We skipped it on Qt to paint the bot green - https://trac.webkit.org/changeset/128167
Please unskip it with the proper fix.

These failures are pixel discrepancies in the line dash pattern. Most probable cause is that GraphicsContext::setLineDash implementation in GraphicsContextQt.cpp does not work as expected. The failing subtest has to do with a non-zero dash offset. That is probably what is causing trouble. I know nothing about drawing with Qt but I suspect the call to QPen::setDashOffset may be the culprit here. Perhaps an issue with the scale or sign of the offset?
