macOS Screen Artifacts.png
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0
Steps to reproduce:
Install Firefox on macOS. Open Firefox. Use Firefox as usual and wait/observe until artifacts appear.
Actual results:
Artifacts atop and below the Firefox window that flicker and move position. They also change color. I've observed orange, magenta, red, green, yellow, and probably more. The horizontal position, color, and number of artifacts seem random. The artifacts temporarily dissapaear if I open/change focus to a different application.
Expected results:
No visible screen artifacts while Firefox is in use.
Hi Novian,
Thanks for reporting this bug.
I'm unable to reproduce it using the latest Firefox Release 68.0.2 and Firefox Nightly 70.0a1 on Mac OSX 10.14.
Any chance you can also try the Nightly build and retest the problem? with a fresh profile and no addons?
Please download Firefox Nightly from here: https://nightly.mozilla.org/
Please also post your Graphic section from about:support, and make sure that you're using latest graphic drivers,
In the meantime, I'll add a product and component so the corresponding team can take a look at this.
Cheers,
I sincerely apologize for the delay. I had reported this bug and moved to Windows for a while. Completely forgot about it.
I tried the latest builds of Firefox stable and Firefox Nightly as of this morning. It occurred in Firefox Nightly after a few minutes of use. While in stable, I attempted to see if anything changed when I plug in my MacBook Pro's power cable, which trigger's automatic graphics switching, prioritizing the more powerful, dedicated graphics card in my system. A few artifacts disappeared when this happened, but one remained. In addition, as I type this, there is an orange colored artifact atop the Firefox window that only flickers in and out while I'm typing. If I stop typing, the artifact disappears until I type again. This is very strange behavior.
Below is the Graphics data from about:support in Firefox stable.

opt-in by default: WebRender is an opt-in feature
WEBRENDER_QUALIFIED:
blacklisted by env: No qualified hardware
It seems I was incorrect about having to wait for the artifacts to appear, but I have to wait a majority of the time. I just fired up Firefox stable (using my less powerful, non-discrete graphics card), and a green-colored artifact appeared immediately. It's flicker changed based on my actions (typing, clicking).
We're starting to get more reports of this, so raising the priority and adding :mstange.

Does anybody see this on Firefox 70 or 71 (currently in Beta / Nightly)?
I'm hoping this has been fixed by the switch to CoreAnimation. We should watch out for reports from people that can see this even with CoreAnimation.
Yes, im observing this regularly, especially when the system temp is higher (ie. watching demanding video on YT for an extended period of time).
Temporairly i disabled hardware acceleration to see if it helps.
I managed to catch it on a screenshot even on cold pc + not even on a webpage, but on the homepage.
... and it even happened when i was writing this post :) Its getting pretty regular. The same operations are fine on chrome/opera/brave/safari.
I would paste those screenshots, but i dont see an option in here.

Today a redditor informed me that disabling automatic graphics switching on their Mac fixed the issue for them.9
