Mis-rendering of parabola in Chrome on Mac El Capitan
I have a bizarre bug, exhibited by https://www.geogebra.org/m/1556391
On Chrome (Version 46.0.2490.86 (64-bit)), running on a MacBook Pro running El Capitan (OSX 10.11.1), when I zoom in using the red slider, the parabola is misdrawn. The parabola is defined as y=x^2, and attached is a screenshot to show an example of the parabola being miscalculated.
The GeoGebra file works correctly in the desktop app, it works correctly in Firefox and Safari, and on Chrome on a colleague's Mac running Yosemite.
It might therefore be a Chrome bug, or some nasty GeoGebra-Chrome interaction, or goodness knows what.
