Flutter dashboard freezes: BindingError: Cannot pass "[object Object]" as a SkPaint*

When I sit on https://flutter-dashboard.appspot.com/#/build and ~2-3 commits come in at the same time, the dashboard starts animating, then eventually freezes and the console starts spewing exceptions.

Exception in console:

BindingError: Cannot pass "[object Object]" as a SkPaint*
    at BindingError.<anonymous> (https://unpkg.com/canvaskit-wasm@0.12.0/bin/canvaskit.js:123:76)

Crashing SkPaint$setAntiAlias is line var thisWired = classParam.toWireType(null, this);

(function anonymous(throwBindingError,invoker,fn,runDestructors,retType,classParam,argType0
) {
return function SkPaint$setAntiAlias(arg0) {
if (arguments.length !== 1) {
throwBindingError('function SkPaint.setAntiAlias called with ' + arguments.length + ' arguments, expected 1 args!');
}
var thisWired = classParam.toWireType(null, this);
var arg0Wired = argType0.toWireType(null, arg0); // bool
invoker(fn, thisWired, arg0Wired);
}
})

Is this still happening?

@yjbanov It is, I just reproduced it on a second machine by sitting on the dashboard for a few minutes. Is there anything specific you'd like me to grab?
