modesetting driver plus DRI3 causes extremely slow scrolling with WebKitGTK+ in accelerated compositing mode

With Epiphany/WebKitGTK+, scrolling on many pages (such as any search results page on duckduckgo.com) is extremely slow and choppy. Launching epiphany with LIBGL_DRI3_DISABLE=1 causes these pages to work perfectly.
This is a critical bug for us since DuckDuckGo is our default search engine.
