This issue was reproduced on Ubuntu 14.04 LTS. On Gtk this works fine. 1056328 1 obzhirov 2014-12-17 07:48:36 -0800 It seems to be related how antialiasing is applied in cairo compositor (which is cairo-spans-compositor.c in the cairo lib used by EFL WebKit). If antialiasing is disabled in GraphicsContextCairo with cairo_set_antialias(platformContext()->cr(), CAIRO_ANTIALIAS_NONE); the problem seems to disappear. 1286368 2 mcatanzaro 2017-03-11 10:38:20 -0800 Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this. 243433 2014-12-17 05:57:16 -0800 2014-12-17 05:57:16 -0800 testcase vertical-glitch.html text/html 474 rgabor PGh0bWw+CjxoZWFkPgogICAgPHN0eWxlPgogICAgICAgIGRpdiB7CiAgICAgICAgICAgIHBvc2l0 aW9uOiBhYnNvbHV0ZTsKICAgICAgICB9CgogICAgICAgIC5ib3ggewogICAgICAgICAgICB3aWR0 aDogMTAwcHg7CiAgICAgICAgICAgIGhlaWdodDogMTAwcHg7CiAgICAgICAgICAgIGJhY2tncm91 bmQtY29sb3I6IGdyZWVuOwogICAgICAgIH0KICAgIDwvc3R5bGU+CjwvaGVhZD4KPGJvZHk+CiAg ICA8Yj5BIHZlcnRpY2FsIGxpbmUgc2hvdWxkIG5vdCBhcHBlYXIgYmV0d2VlbiB0aGUgYm94ZXMu PC9iPgogICAgPGRpdiBzdHlsZT0ibGVmdDogMHB4OyB0b3A6IDUwcHg7IHdpZHRoOiAxMjgwcHg7 IGhlaWdodDogNzIwcHg7Ij4KICAgICAgICA8ZGl2IGNsYXNzPSJib3giID48L2Rpdj4KICAgICAg ICA8ZGl2IGNsYXNzPSJib3giIHN0eWxlPSJsZWZ0OiAxMDBweDsiPjwvZGl2PgogICAgPC9kaXY+ CjwvYm9keT4KPC9odG1sPgoK
