I'm experiencing an issue with Firefox on Ubuntu 18.04 having no 2D acceleration, 3d seems to work fine, but scrolling, switching tabs, and watching YouTube and Netflix has noticeable tearing. I have the nvidia-driver-396 driver. The same issues are present with the nvidia-driver-390 driver. OpenGL games work fine, so it's not OpenGL. And I have Hardware Acceleration enabled in Firefox settings. My GPU is an Titan Xp, and Ubuntu is up-to-date and I have third party properaty things enabled on install.(for audio codecs)
Anyone know what might be the issue?
