Weird behavior in Firefox Quantum #233

Closed alexstojda closed 6 years ago

alexstojda commented 6 years ago

I have this weird behavior that I cant really describe well. if the top of a section below a parallax container scrolls off the page, then you scroll back to it, it appears to get "caught" by the top of the viewport before snapping back to its proper size.

This is illustrated in the gif below, with the three frames containing the phenomenon elongated, pay attention to the space above the "Engineering & Computer Science..." text.

Firefox Version: 57.0.2 (64-bit)

I'm also receiving the same response on my personal website within Firefox Quantum (Version 57.0.1 - 64-bit).

Will need to try and roll back to a previous version of FF to isolate if the bug is within Parallax.js or Quantum.

Sunday December 17 edit: http://pixelcog.github.io/parallax.js/ works fine when viewed in FF Quantum - suggests it might be something locally..

I wonder if it's connected to this regression https://bugzilla.mozilla.org/show_bug.cgi?id=1424506

@alexstojda - this behaviour should have been fixed with one of the latest updates to Firefox. Can you try to recreate it once more?

alexstojda commented 6 years ago

@SeanPrashad its much less apparent, but if you have an eye for detail its still there every so slightly

since this seems to be an issue with Firefox Quantum rather than this library, i will close this issue
