I see that in this one you don't seem to have touch input enabled (your about:support output says wheel input only), so I'm not going to make this block bug 1244402. Probably still needs investigation though.
Sorry it couldn't attach last time because of large size. Here is the link https://ranisharma22.tinytake.com/sf/OTQyNjgwXzM5NjU0MzU
Another video of bug: https://ranisharma22.tinytake.com/sf/OTQyNzYyXzM5NjU2NDQ
I couldn't access the link in comment 2 - permission denied. I saw the video in comment 3, and it looks like checkerboarding. However I'll try again to reproduce locally and confirm. Also in the about:support in the video it showed that touch input was enabled, which contradicts what you said in comment 0.
I followed the steps and I can get a little bit of checkerboarding but nothing much. It's transient and goes away almost immediately. Kanchan, do you still see this problem? In particular I'm interested in behaviour that's worse than just a little checkerboarding.
Hello Kat, I still see this issue. https://ranisharma22.tinytake.com/sf/MTAyNzI3OF80MjAwNzcx Yes, this seems checkerboarding issue as with layers.async-pan-zoom.enabled; false, it's not reproducible.
Thanks, that does look like regular checkerboarding. I'll dupe this over to the main checkerboarding bug.
