Purple tinted GXR display .... anyone else seen this?

I have started to get a pronounced purple tint in both the EVF and the LCD very ocassionally as I switch between full screen magnified and standard image. It only happens when I have the A12 M mounted and it clears as soon as I switch again. It does not affect the image.

And it only started to happen after I upgraded to the new firmware.

Is anyone else seeing this?

It's doubly frustrating because i can't identify a single set of circumstances in which the problem appears. And it only happens very 50 or so shots.

Annoying ......
