Hello, I am using firefox v 60.0b15 installed from AUR. My hardware is: 1. AMD 1600 Processor 2. nVidia 1500Ti GPU running nVidia proprietary driver 3. 16GB 3200MHz RAM There should not be any problem running firefox with this configuration but I am facing weird lag and screen tearing when I turn on smooth scrolling. Things I have tried: 1. Enabled / Disabled hardware acceleration 2. Applied 1.2, 1.3, 1.6, 1.8, 1.10, 1.11 from https://wiki.archlinux.org/index.php/Firefox/Tweakshttps://link.getmailspring.com/link/1524668509.local-c70ad352-4319-v1.2.1-7e7447b6@getmailspring.com/0?redirect=https%3A%2F%2Fwiki.archlinux.org%2Findex.php%2FFirefox%2FTweaks&recipient=YXJjaC1nZW5lcmFsQGFyY2hsaW51eC5vcmc%3D I had scrolling issue before trying anything, still have them. My desktop environment is KDE and Kernel version is 4.16.3-1-ARCH. I have all the updates installed. What can I do to make the tearing go away? Turning off smooth scrolling does solve the issue but I'd like to keep it on. Thanks C
