Hi, thanks for reporting! That one is really weird. I have no idea how this could affect webgl, but I confirm it's there. This is also to be expected to still not work after disabling globally or on domain from the popup with the current version, because I still apply the CSS3 filter with invert and hue-rotate, I just give it parameters of 0. In the new version (hopefully coming sometime soon) that will be different, enabling you to at least rather conveniently disabling globally/on domain before loading G Maps etc. and also that super stupid bug where prints are pixelated because it doesn't bother to recalculate the pixel buffer for the significantly higher resolution. (Yes, really. That took me a while to figure out. *facepalm*)
