Scrolling in firefox snap

hvbakel · November 16, 2020, 11:06pm

For the most part the the firefox snap behaves very similar to the deb counterpart, with the exception of scrolling. The snap version is noticeably less smooth and after some searching it seems this may be due to the fact that the deb version has xinput support enabled by default. Has anyone found a way to have the same scrolling behavior in the snap version?

The Snap seems OK to me, but I have

export MOZ_USE_XINPUT2=1

in my .profile. Try adding that to yours and see if it helps.

I experience a very bad scrolling only when two FF snap windows are open (e.g. 1 normal 1 private).
Do you see that running 1 window too?

After some more digging it turns out that I had changed the setting general.smoothScroll.mouseWheel.migrationPercent to 0 at some point in the past in the deb profile. After making the same change in the snap version the scrolling behavior is identical. Setting MOZ_USE_XINPUT2=1 didn’t make any difference in behavior for the firefox snap.
