SUMMARY Dear Falkon devs: When I open this URL the background image (a jpg) does not render correctly (please see side-by-side comparison with Firefox screenshot https://i.imgur.com/l3GJLJL.png ) It might be related to this (quite dated) bug https://bugs.kde.org/show_bug.cgi?id=22126 ) STEPS TO REPRODUCE 1. Visit the page https://www.dignityincare.ca/en/ 2. 3. OBSERVED RESULT It does not render the image, displaying the characters, see https://i.imgur.com/l3GJLJL.png EXPECTED RESULT It should render the JPG image correctly. If it's something related to flash, then it probably should display a warning message.
