Description
When I open the attached file (which just contains 65536 lines with 64 "a"s each) in Demo Browser, Minimal Browser, Simple Browser, ... and scroll down, the rendering becomes very slow. It manages to render about 240 lines, then it takes seconds to catch up, so I can scroll down another 100 lines etc.
It works much better in chromium-browser, chrome and firefox. I have tried passing my chrome://flags settings via commandline switches to webengine.
