Caused by background-size: contain, introduced in T85139, together with many em measurements multiplied together – all these thousandth parts of ems multiplied together actually cause rounding errors significant enough to cause bad rendering (elements a pixel bigger/smaller than they should be). T93636: Indicator distorted in Firefox 31.5.0 is probably the same thing as here, but in Firefox and on indicators only.

Edge has issues with width/height in em & scaling of indicatorElement-indicator and iconElement-icon and background-size: contain :
