When you zoom in / out, the slash and 'D' elements are no longer displayed correctly. This is probably because we store two members m_ascent & m_contentRect on the renderer class and thy are not updated when zooming in / out. In general, in the past the solution for this kind of problem has been to get rid of these members. That's at least easy for m_ascent. 1376028 1 fred.wang 2017-11-29 14:14:34 -0800 @Jacques: Do you still have the issue? I can't reproduce it with the testcase on WebKitBuild nightly or epiphany release. 1376185 2 distler 2017-11-29 18:50:52 -0800 Seems to work fine now (Safari 11.0.1 (12604.3.5.1.1), MacOSX). And it does not seem to be an issue in iOS 11.1.2 either. 1376242 3 fred.wang 2017-11-30 00:08:40 -0800 Thanks. I'm not sure what resolved this. Maybe bug 161127 helped but it was probably not enough. Also, there was bug 160077 where I worked on that Dirac equation too but I don't remember exactly. Let's marked it as fixed. 286836 2016-08-23 23:34:11 -0700 2016-08-23 23:34:11 -0700 Testcase dirac-equation.html text/html 579 fred.wang PCFET0NUWVBFIGh0bWw+CjxodG1sPgogIDxoZWFkPgogICAgPHRpdGxlPkRpcmFjIEVxdWF0aW9u PC90aXRsZT4KICAgIDxtZXRhIGNoYXJzZXQ9InV0Zi04Ii8+CiAgPC9oZWFkPgogIDxib2R5PgoK ICAgIDxtYXRoIGNsYXNzPSJtYXJ1a3UtbWF0aG1sIiBkaXNwbGF5PSJibG9jayIgeG1sbnM9Imh0 dHA6Ly93d3cudzMub3JnLzE5OTgvTWF0aC9NYXRoTUwiPjxzZW1hbnRpY3M+PG1yb3c+PG1lbmNs b3NlIG5vdGF0aW9uPSJib3giPjxtcm93PjxtbyBzdHJldGNoeT0iZmFsc2UiPig8L21vPjxtaT5p PC9taT48bWVuY2xvc2Ugbm90YXRpb249InVwZGlhZ29uYWxzdHJpa2UiPjxtaT5EPC9taT48L21l bmNsb3NlPjxtbz4rPC9tbz48bWk+bTwvbWk+PG1vIHN0cmV0Y2h5PSJmYWxzZSI+KTwvbW8+PG1p Ps+IPC9taT48bW8+PTwvbW8+PG1uPjA8L21uPjwvbXJvdz48L21lbmNsb3NlPjwvbXJvdz48YW5u b3RhdGlvbiBlbmNvZGluZz0iYXBwbGljYXRpb24veC10ZXgiPlxib3hlZHsoaVxzbGFzaHtEfStt KVxwc2kgPSAwfTwvYW5ub3RhdGlvbj48L3NlbWFudGljcz48L21hdGg+CiAgICAKICA8L2JvZHk+ CjwvaHRtbD4K
