Up until now I w= as using the built-in graphics in my AMD processor. I don't remember having any issues. However, after switching to nVidia and downloaded nvidia-drivers package I started noticing tearing/skipping artifacts when scrolling in Firefox. Since I'm new to nvidia tools and configurations, I've spent sever= al days trying to find what is causing the tearing problem while mainly suspec= ting the driver or KDE. At some point I've noticed that this tearing problem is happening only in Firefox, and resizing/moving windows around the screen was smooth. So, apparently the problem was neither in the driver nor KDE, but in Firefox. I've checked what is written in about:support and noticed the following: HW_COMPOSITING: available by default, blocked by env: Acceleration blocked = by platform After forcing the hw compositing with `layers.acceleration.force-enabled=3D= True` in about:config scrolling became silky smooth.=20 So, is there a reason for disabling hardware compositing by default? In my opinion, with the state of nvidia and amd drivers currently, most of the us= ers would expect these relatively basic accelerations to be enabled by default.= If they have problems with something, just then should they try to disable the problematic feature. If there are serious problems, then at least a post-installation message pointing the user to enable acceleration will be = very beneficial in both performance and tearing-free experience.
