0x23b254, length 0 No errors detected in policies.google.com_terms_hl=en.png (288 chunks, 96.6% compression). What is the expected behavior? All pngs exported via the `Capture full size screenshot` method should contain visual content matching the website. What went wrong? Images were viewed in OSX Preview: - privacy: transparent = erroneous. - policies: as expected = pass. Win7 Windows Photo Viewer: - privacy: transparent | black = erroneous. - policies: as expected = pass. GIMP 2.8 OSX: - privacy: transparent = erroneous. - policies: as expected = pass. GIMP 2.8 Win7: - privacy: transparent = erroneous. - policies: as expected = pass. This seems to be a problem with the layout of some web pages when attempting to capture the full size screenshot. Did this work before? N/A Chrome version: 66.0.3359.139 Channel: stable OS Version: OS X 10.13.4 Flash Version: AFAIK this worked before, as I have never encountered this problem until today, where I encountered it many times, and I have been using the feature almost daily recently.

I just tried `Capture full size screenshot` on https://newrelic.com/termsandconditions/privacy on OSX, it beachballs for a few seconds and fails to yield a png whatsoever. I then closed Devtools and typed a search query into URL bar, google.com could then not be scrolled (no scrollbar, attempts to scroll down with Macbook pad just bounce back up )). Cray cray. |
