User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0 Build ID: 20170413192749 Steps to reproduce: Scrolling fast on pages (This is on Linux Mint Cinnamon 64 with Nvidia 387.12 and Nightly 59.0a1 (2017-11-24) (this issue has been there for a while though) Actual results: there is screen tearing happening. Expected results: It should be smooth. Setting layers.acceleration.force-enabled to true fixes the tearing, but makes firefox crash way too often, very unstable.
