layers.acceleration.force-enabled = true & layers.force-active = true seem to solve my screen tearing and graphical glitches on Ubuntu 18.04...any risks?

I had screen tearing and graphical glitches when browsing. [layers.acceleration.force-enabled = true] solved screen tearing, but I still had some graphical glitches from time to time which now seem to have been fixed with [layers.force-active = true].

Could this be a working configuration on the long term? Currently it is running like a charm...

I'm running Ubuntu 18.04 and had already turned off hardware acceleration and smooth scrolling without the desired results before trying the above-mentioned things. I also played around with the xorg.config.d settings of the OS...

Best regards Mike

Basically you are just forcing Hardware acceleration to run. The only risk is that it could break in the future, but then you'd just disable it. I'd suggest keeping your graphics drivers up to date along with Firefox, but otherwise it'll be fine (hopefully)

Thank you Tyler for your reply!

Found a better solution. Setting gfx.xrender.enabled=true and layers.acceleration.force-enabled & layers.force-active back to default solves everything.

How do you believe this is better than forcing hardware acceleration?

I'm on Ubuntu 18.04.1, Firefox 64.0 and I'm going through the same problems as you.

With layers.acceleration.force-enabled=true you get a very smooth scrolling experience, but sometimes graphical glitches and artifacts happen - e.g. on the Ubuntu Certified Hardware website when hovering over the different manufacturers. Setting layers.force-active= true will solve this issue. In terms of performance this wasn't really good. Seemed to slow down everything. Setting both to default again and gfx.xrender.enabled=true will make everything feel snappier and faster again without graphical issues and tearing. This is why I believe it to be a better solution...just my opinion. I'm still doing it that way. Hope it helps...
