336	2x scaling errors with Mac retina display	Tom Goddard	Tom Goddard	"On a Macbook Pro with retina display (Mac OS 10.11.5) and Qt 5.6.0 the graphics shrinks to half size occupying the lower left corner when the window is resized.  Rotating makes it then return to full size.  Enabling silhouette edges shows the edges scaled 2x larger than the full window.

The Mac retina implementation requires requesting an OpenGL context to get the full retina resolution. It seems Qt is sometimes providing full resolution sometimes half.  Maybe it is just reporting the window width/height off by a factor of 2.

These problems do not occur on non-retina Mac 10.11.5 system."	defect	closed	major		Platform		fixed						all	ChimeraX
