Expected results: Stay quiet.

Setting image.high_quality_downscaling.enabled = false fixes the CPU problem

The chess pieces are draw at two different sizes, both of which aren't the original image size. So this is the same "resize to size 1, resize to size 2, resize to size 1, ..." loop we suffer from that Seth is working on fixing.

That bug should be fixed now. We should retest this.

(In reply to Timothy Nikkel (:tn) from comment #4) > That bug should be fixed now. We should retest this. It looks fixed to me; I can't reproduce the high CPU usage or the blinking. Seems like this was resolved by classic bug 1060869.

Thank you for the confirmation.
