When I try to open a pdf on a certain site I get the pdf, but there is an overlay of a pencil editing a ghost document. How can i get rid of this overlay? I've tried everything.

There should be a button to dismiss it, but it looks like you may be too zoomed in to see it.

Try zooming out several times (by pressing CTRL and the - key (minus). That may enable you to see it and dismiss the popup.

Afterwards, press CTRL and 0 to reset to your default zoom setting.

Didn't work. Probably a scaling issue, but that window does not react to <ctrl, - >, so cannot see close button, would be nice if it was a standard win window with minimize and close at the top. No hurry, it worked in chrome.
